Practice C# questions

• I want to implement a class named MyClass. What shall I name the file?
• What line do I type to compile the code on a unix-based machine?
• What line do I type to run the code on a unix-based machine?

Consider the following code:
A.cs
B.cs

• What type of function is public A(int x)?
• What type of function is public int getNumber()?
• What is the output from running main in A?
• I would like to be able to print out like this:
  Console.WriteLine("A: "+a+"\n");
  Implement the function that will allow this.

Now imagine that I have these two classes: SubA.cs and SuperA.cs

• In order to allow SubA to directly access instance variable number, what keyword do I need to use when it is declared?
• What does the line base(x*2) do?
• What is the output of running main in SubA?
• How does the computer decide between calling SuperA or SubA's version of getNumber?
• How does the computer decide between calling SuperA or SubA's version of setNumber?
• Explain why the following line of code is not allowed: SubA a1 = new SuperA(7);
