Introduction to Functions in C#
In C#, a function is a way of packaging code that does something and then returns the value.à Unlike in C, C and some other languages, functions do not exist by themselves. They are part of an object-oriented approach to programming. A program to manage spreadsheets might include a sum() function as part of an object, for example. In C#, a function can be called a member functionââ¬âit is a member of a classââ¬âbut that terminology is left over from C. The usual name for it is a method. The Instance Method There are two types of methods: instance method and static method. This introduction covers the instance method. The example below defines a simple class and calls it Test. This example is a simple console program, so this is allowed. Usually, the first class defined in the C# file must be the form class. Its possible to have an empty class like this class Test { }, but it isnt useful. Although it looks empty, itââ¬âlike all C# classesââ¬âinherits from the Object that contains it and includes a default constructorà in the main program. var t new Test(); This code works, but it wont do anything when run except create an instance t of the empty test class. The code below adds a function, a method that outputs the word Hello. using System;namespace funcex1{class Test{public void SayHello(){Console.WriteLine(Hello) ;}}class Program{static void Main(string[] args){var t new Test() ;t.SayHello() ;Console.ReadKey() ;}}} This code example includes Console.ReadKey(), so when it runs, it displays the console window and awaits a key entry such as Enter, Space or Return (not the shift, Alt or Ctrl keys). Without it, it would open the console Window, output Hello and then close all in the blink of an eye. The function SayHello is about as simple a function as you can have. Its a public function, which means the function is visible from outsideà the class. If you remove the word public and try to compile the code, it fails with a compilation error funcex1.test.SayHello() is inaccessible due to its protection level. If you add the word private where the word public was and recompile, you get the same compile error. Just change it back to public. The word void in the function means that the function does not return any values. Typical Function Definition Characteristics Access level: public, private plus some othersReturn value: void or any type such as intMethod Name: SayHelloAny method parameters: none for now. These are defined in the brackets () after the method name The code for the definition of another function, MyAge(), is: public int MyAge(){return 53;} Add that right after the SayHello() method in the first example and add these two lines before Console.ReadKey(). var age t.MyAge();Console.WriteLine(David is {0} years old,age); Running the program now outputs this: Hello David is 53 years old, The var age t.MyAge(); call to the method returned the value 53. Its not the most useful function. A more useful example is the spreadsheet Sum function with an array of ints, the start index and the number of values to sum. This is the function: public float Sum(int[] values, int startindex, int endindex){var total 0;for (var indexstartindex; indexendindex; index){total values[index];}return total;} Here are three use cases. This is the code to add in Main() and call to test the Sum function. var values new int[10] {1, 2, 3, 4, 5, 6, 7, 8, 9,10};Console.WriteLine(t.Sum(values,0,2)); // Should be 6Console.WriteLine(t.Sum(values,0,9)); // should be 55Console.WriteLine(t.Sum(values,9,9)); // should be 10 as 9th value is 10 The For loop adds up the values in the range startindex to endindex, so for startindex 0 and endindex2, this is the sum of 1 2 3 6. Whereas for 9,9, it just adds the one values[9] 10. Within the function, the local variable total is initialized to 0 and then has the relevant parts of the array values added.

Marriott has also adopted the market penetration strategy through its ââ¬Å"Love Travelsâ⬠campaign that portrays the companyââ¬â¢s dedication to make every person feel comfortable for who they are whenever they travel (Marriott News Center, 2014) Marriot Incorporation has also made use of the market development strategy. This strategy centers on developing new markets for the organizationââ¬â¢s existing products and services (Oh, 2009). In the context of Marriot, the company has grown to other markets through building new units and joint ventures. One of the regions that Marriot Incorporation has focused on is the markets outside United States (Marriott News Center, 2014). This is because the growth rates within United States have gone down thus offering opportunities to expand to other regions. Some of the regions that companies expand to offer more lucrative business opportunities. Recently, Marriot bought out Delta chain of Hotels in Canada after the recent Canadian economic turmoil (Brownell, 2015).

The company anticipates that the weak Canadian Dollar will encourage more Europeans and Americans to travel to Canada. Marriot bought Delta chain of hotels from the British Columbia Investment Management Corporation at 168 million US dollars. By buying the Delta, Marriot will have control of 30 hotels within Canada (Brownell, 2015). The company also recently expanded to Italy in Sacca Sessola, a few minutes away from Venice. By the end of 2015 the company also anticipates to have acquired 20 hotels in more than 20 countries.

Analysis Of The Short Story Collection Prince Valiant ,...
Owen Marshall wrote the short story collection: ââ¬ËPrince Valiantââ¬â¢, ââ¬ËThe Fat Boyââ¬â¢, ââ¬ËMr Van Goghââ¬â¢, and ââ¬ËThe Ace of Diamonds Gangââ¬â¢, approximately several years, he decided to concentrate on his writing to illustrate the key important ideas or conflicts in society of overcoming ostracism. His collection of ostracizing stories stood out for me because relationships are very important to our day to day lives as we are constantly interacting with different people among our society. We read about his stories in first person and second person, which makes it appear simple on the surface, yet it still contains complex and structured ideas. Owen Marshall was raised up in a family in which the world of literature and that of physical experience were equally valued. I chose ââ¬ËPrince Valiantââ¬â¢, ââ¬ËThe Fat Boyââ¬â¢, ââ¬ËMr Van Goghââ¬â¢, and ââ¬ËThe Ace of Diamonds Gangââ¬â¢ short stories. I chose these because they all revolve around a similar idea: Ostracization. We can know more about relationships, to get a better understanding through short-stories about important characters. Many people in the town think this character is strange and often tease him/her. Whether this is the conflict of morals seen in ââ¬ËThe Fat Boyââ¬â¢ or the struggle to retain sanity displayed in ââ¬ËThe Ace of Diamonds Gangââ¬â¢. Owen Marshall is suggesting to society that ostracizing differences is harmful, both physically and, more importantly, psychologically. Itââ¬â¢s common in society such as in the city which treats somebody as a complete

The House on Mango Street Fantasy vs. Reality Ho Essay Example For Students
The House on Mango Street Fantasy vs. Reality Ho Essay use Mango Street The House on Mango Street Fantasy vs. Reality Sometime in our lives, we have wished for things we dont have. No matter how hard we wished on the star or a candle, our wishes never seemed to be answered. We have all felt that bitter disappointment on Christmas morning when we finally realized that we were never going to be able to have what we want. This is the same exact feelings that the characters in Cisneros The House on Mango Street. Unlike us, the disappointment for these characters last throughout their childhood. Esperanza, Rachel, Nenny, Sally, and Lucy are among the kids growing up on Mango Street. They all long for friendship, love, and a better life, but all these kids face are the harsh reality of the real world. In the society that Esperanza and her friends live in, love takes a back seat when it comes to relationships. Someday, I will have a best friend all my own. One I can tell my secrets to. One who will understand my jokes without my having to explain them. These are the longing words of Esperanza. While growing up on Mango Street, Esperanza finds herself in a community that she feels she doesnt belong to. With all her heart, she longs for a true friend that she can tell her dreams to and will understand her for it. These wishes seem easy enough to grant, but Esperanza soon finds out that there is more to friendship. If you give me five dollars, I will be your friend forever. Esperanza discovers that she can not have anything for nothing. Rachel and Lucy sure enough become her friends, but only after she helped them pay for the bike. Esperanza never does truly find a real friend who shares the same goal as she does because all the friends she has have more problems than her. For instance, Sally was a friend for whom Esperanza cared for. When Esperanza was raped, Sally was not there to help her and when Esperanza tried to prevent Sally from making a mistake, Sally told her to leave. All Esperanza wanted was a friendship that would help her escape her life, but all she ended up with were friendships that reminded her of her broken dreams because in her society nothing was given for free and the people she was associated with didnt have the same goals as she did. Another one of those broken dreams was the concept of love. Esperanza was not the only one who longed for a mans endless love. Marin, Esperanza, Rafaela, and Sally are all waiting for a car to stop, a star to fall, someone to change her life. These girls are all waiting for prince charming to come and sweep them off their feet. They believe that the right man will come and love them for who they are and take them away to a nice house. Marin says that she will move in and marry her boyfriend, but the harsh reality is that she will only be sent to a worse life. Cisneros uses the story of Rapunzel to describe Rafaelas life. She longs to be free of the tower and do as she pleases, but all she gets is a husband who keeps her locked up in the apartment and that is where she will remain. In Sallys case, she wants a man to love her and she thinks she can achieve that by using her body. Sally eventually gets married to a man who provides her with riches, but she will never be an individual.

Nothing about love that was told to her turned out to be true after she experienced what men thought of as love. In all respects, the thing that the characters in The House on Mango Street strived for was a better life. This proved true in the case of Esperanza. A fairy tale element that was used was the Old Lady who had so many children. The old lady would just gripe about her misfortune and neglected what was granted .

Hudson River School free essay sample
While both works prominently feature New England landscapes, there are a few key differences that result from vast differences in artistic style. Oââ¬â¢Keeffe, staying true to her modernist roots, depicts her landscape in a simplified or abstracted form by omitting major details from her scene, and also through non-representational color choices. Contrasting this, Bierstadt gives his scene intense detailing while simultaneously idealizing the scene and presenting nature in its most romantic form, thus offering a picturesque representation of the landscape with obvious omissions of human presence or natural flaws, which serves to enhance his scene. It is immediately clear that both landscapes, in their simplest form, depict a very similar subject: New England mountains and water. Bierstadt presents a majestic take on his landscape, which uses sunlight to emphasize a mist hovering above the lake in the foreground. This misting highlighted by the sun gives the landscape an overwhelmingly divine feeling to it. Contrasting this divine feeling, Oââ¬â¢Keeffeââ¬â¢s work evokes more of a sense of calmness. With a full pink moon displayed in the background, its reflection in the water, and a series of green mountains in the foreground, the landscape moves in a more mystical yet tranquil way than the other work. Her ocean stays relatively still, with only slight movement evoked by visible brush strokes, as opposed to the active transformation from water to mist in Bierstadtââ¬â¢s lake. Also, where his mountains serve as fixed objects in the landscape, Oââ¬â¢Keeffeââ¬â¢s mountains seem to be rolling in a more literal sense. The fading of colors gives them an undulating feel that starkly contrasts the Franconia Mountains depicted. Pink Moon Over Water, although similar in style to most of Georgia Oââ¬â¢Keeffeââ¬â¢s work, differs in that it depicts a scene from Maine (Oââ¬â¢Keefee). Most of her work was inspired from living in Arizona, where she spent most of her life (Biography). In a similar manner, although most of Albert Bierstadtââ¬â¢s work depicted the American West, this landscape differs in that it represents a setting in New Hampshire that is much closer to his hometown of New Bedford, Massachusetts (Henderson). Echo Lake, Franconia Mountains, New Hampshire, belongs to the artistic movement that classifies all off Albert Bierstadtââ¬â¢s work: The Hudson River Schoolââ¬âa mid-nineteenth century American art movement that embodied elements of realism and romanticism (Henderson). Both of these criteria are met; the landscape is extremely detailed, making it seem for the viewer as if they are standing and witnessing it in person, while at the same time it is idealized by being stripped of any human presence which likely would have existed at the time of the works creation (Curatorââ¬â¢s). Another romanticized element in play is the depiction of the light as it perfectly spotlights the ominous misting from the lake. From this it is clear that the work remains within the bounds of the Hudson River School movement of which Bierstadt pioneered, because such a spontaneous set of circumstances would not likely have occurred during the creation of the work. Very different in style, Pink Moon Over Water belongs to the American modernist movement. Characteristics which can attribute it to the movement include abstraction for the sake of aesthetic pleasure and the rejection of realism. Much like many of Georgia Oââ¬â¢Keeffeââ¬â¢s other paintings, Pink Moon attempts to escape reality purposefully in an attempt to increase its visual appeal. Rather than a rigid or earthly form, Oââ¬â¢Keeffe gives her mountains a smoothness that does not exist in nature. She reshapes the environment and fashions it in a way that happily and eagerly attempts to agree with the human eye. Major compositional elements in Pink Moon Over Water, include mountains, ocean, and a pink full moon. In this sense, the piece is simplistic because it does not have any minor elements like trees or clouds. Although the rolling foreground mountains make the landscape asymmetrical, it is very close to being a symmetrical piece. Color distribution is very even and the moon is a perfect circle centered in the background, and because of this the work effectively tip-toes the line between symmetry and asymmetry. Contrasting this is Echo Lake, which is clearly asymmetrical: on the right is a lake and distant mountains, and on the left a shore and closer mountain with trees. Because of its intricate detailing, the New Hampshire landscape possesses many elements which were thoughtfully excluded from the Pink Moon Over Water landscape. These elements include trees, shrubs and vegetation, clouds, rocks, and mist. Although itââ¬â¢s likely all of these details would have been present at the location of Georgia Oââ¬â¢Keeffeââ¬â¢s work, she chooses not to display them for the sake of smoothness and aesthetic indulgence that is characteristic of her artistic style. There are huge differences in the application of color between the two works. Albert Bierstadt uses color in his landscape with one purpose in mind: accurately depicting the subject matter in its ideal state. Earthly tones are used for the dirt and mountains, lush green shades for the vegetation, and soft blue tones for the sky and its reflection on the lakeââ¬â¢s surface. Although slightly idealized, the colors reflect something that can unquestionably be found in nature. Georgia Oââ¬â¢Keeffe contrastingly takes her work in the opposite direction. Itââ¬â¢s clear at first glance that the colors she uses, although beautiful and calming, could never be found in nature. She applies greens that range from whitish and sea foam green colored to a pine green color at the tops of the mountains. Most notably of all, the moon is a light shade of pink that serves as a perfect complement to the greens used in the mountain. Light is another element used very differently in both landscapes. In Echo Lake, dark storm clouds dominate the top of the landscape, but a gap exists that allows a radiant beam of sunlight to penetrate, which serves to showcase the mist coming up from the lake. This effectively gives the mist a divine feel that elevates the landscape to something more powerful than just a simple mountain scene. Oââ¬â¢Keeffeââ¬â¢s painting uses light much differently. The source of light is the reflection of the moon. Aside from its reflection on the water, it is unclear how the moonlight affects the rest of the piece. Irrationally, mountain peaks which have more exposure to the moonlight are darker, while the lower parts of the rolling hills that are tucked away from the moonlight are brightly colored. Because of this it is clear that Oââ¬â¢Keeffe intended to use light for a different purpose. The fading from light to dark in the mountains gives them a strange sort of movement while viewing it. Starting from the bottom, the viewerââ¬â¢s eyes can almost roll over each individual hill and then finally into the water off in the distance. Spatially, both landscapes are ordered very logically. It is not hard to discern what elements come in front of or behind other elements. It is clear in Pink Moon Over Water that closest to the viewer is three distinct hills that lead into a distant ocean and horizon. Similarly, Echo Lake presents little challenge. In the foreground is a lake and shoreline, which leads to a mountain farther back, and finally a distant mountain and clouds. Brushstrokes are easily seen in Pink Moon Over Water, while they are challenging to spot in Echo Lake, Franconia Mountains, NH. Albert Bierstadt did well to conceal the appearance of any brushstrokes. His attention to detail and high level of skill attempts to minimize the appearance of brushstrokes, most likely to avoid reminding the viewer that this is indeed a painting, and not a photograph. Oââ¬â¢Keefe on the other hand used visible brushwork to give her mountains and water horizontal motion. When I look at Bierstadtââ¬â¢s Echo Lake and the powerful natural environment it depicts, I simply feel as if it immediately takes me to New Hampshire, and quietness envelops my mind. It reminds me of the peaceful serenity thatââ¬â¢s characteristic of the natural environment. In addition, the transformation from water to mist feels symbolically representative of the physical laws that govern us. It reminds me that we as humans simply populate a natural world that possesses infinitely more power than we do. Although I both admire and respect the scene portrayed by Bierstadt, I prefer Oââ¬â¢Keeffeââ¬â¢s work because I connect better to it emotionally. The abstraction and unique color choices allow for an escape from reality that is not possible in Bierstadtââ¬â¢s work. Even though it does not depict a realistic landscape, it still manages to convey a kind of surreal tranquility ordinarily evoked from the most beautiful and monumental landscapes. Even though both landscapes discussed are set in New England, the similarities end there. Echo Lake, Franconia Mountains, NH offers a straight forward and accurately detailed look at a mountain landscape, which opposes the abstracted view of a landscape presented in Pink Moon Over Water, which makes use of non-representational color and simplified natural forms. Rather than idealizing her scene like Bierstadt, Georgia Oââ¬â¢Keeffe simplifies it. Both convey powerful emotions and go in very different directions to do so.
