1. Write a snippet of code that asks the user for their name and prints out "Hello X" where X is their name.
   
2. What does the following code do?
   
   for(int i=0; i < 3000; i += 3)
   {
     Console.WriteLine(i);
   }
   
3. Write a snippet of code that reads in four numbers from the user and displays the smallest of the four numbers.
   
4. Describe the difference between the WHILE, FOR, and DO-WHILE loops.  When is it appropriate to use each?
   
5. Describe the similarities between the WHILE, FOR, and DO-WHILE loops.
   
6. What does the following code do?
   
   int i = 4;
   int j = 10;
   
   if ((i < 7) && (j < 10))
   {
     if (i + j < 20)
       Console.WriteLine("A");
     else
       Console.WriteLine("B");
   }
   else
   {
     if (i + j < 20)
       Console.WriteLine("C");
     else
       Console.WriteLine("D"); 
   }
   
7. Write a code snippet that repeatedly prompts the user to type "QUIT" and reads in a string from the user until the user types "QUIT".  You must use a do-while loop in your solution.
