Part 1

1. a. Create a class named Numbers whose Main( ) method holds two integer variables.

Assign values to the variables. Within the class, create two methods, Sum( ) and

Difference( ), that compute the sum of and difference between the values of the two variables, respectively. Each method should perform the computation and display the results. In turn, call each of the two methods from Main( ), passing the values of the two integer variables. Save the program as Numbers.cs.

b. Add a method named Product( ) to the Numbers class. This method should compute

the multiplication product of two integers, but not display the answer. Instead, it should return the answer to the calling Main( ) method, which displays the answer.

Save the program as Numbers2.cs. (Note: For All code only use only the code that is necessary not all the extra items that Visual Studio adds.)

2. Create a class named Square. In the Main( ) method, declare an integer and prompt the user for a value. Display the value of the integer, then pass it to a method that accepts the value as a reference parameter and prints its square (the number times itself). In Main( ) , print the value again, proving that the original argument to the method was altered. Save the program as Square.cs.

Part 2

1. Create a class named Game that contains a string with the name of the Game and an integer that holds the maximum number of players. Include properties with get and set accessors for each field. Also, include a ToString( ) Game method that overrides the Object class's ToString( ) method and returns a string that contains the name of the class (using GetType() ), the name of the Game, and the number of players. Create a child class named GameWithTimeLimit that includes an integer time limit in minutes and a property that contains get and set accessors for the field. Write a program that instantiates an object of each class and demonstrates all the methods. Save the file as GameDemo.cs.
