//                 In-Class Assignment 5
//                Count-controlled loops
//
// 1. Save a copy of this program on your disk. Then open the
//    program in your C++ program editor.
//
// 2. This program calculates and prints the sum of the integers
//    from 1 to 10. Run the program to verify this.
//
// 3. Modify the program to calculate and print the sum of the
//    integers from 1 to 20. Run your program to verify that it
//    works correctly. Turn in a listing of your program. Be
//    sure your name is on it.
//
// 4. Optional: Try to modify your program so that it calculates
//    and prints the sum of the even numbers between 1 and 21.
