15. The class ContDemo in this chapter shows one way to use a for loop to print the even numbers from 0 to 100. Write programs that print the same output as that program, but do it in the following ways: A. Using a for loop that increments the loop control variable by 2 each iteration.

b. Using a for loop whose loop control variable goes from 0 to 50.

C. Using a for loop whose loop control variable goes from 100 down to 0.

D. Using an infinite for loop with no conditional expression and exiting the loop with a break statement.

E. Using a while loop.

F. Using a do-while loop.
