Several people have asked for some practice problems to help get ready for the first quiz on loops. Here are a few such problems: one that uses WHILE loop and one that uses FOR loops. If you can do these you should know what you need to know for the quiz:
A. Write a program that lets the user enter numbers, one number
at a time, until the user finally enters 0. The program should then print
out the average of these numbers. For example:
Enter a number:
3
Enter a number:
4
Enter a number:
8
Enter a number:
0
The average
of those 3 numbers is 5.0
Of course, to find the average you need to keep a running total of all of
the numbers that have been entered, and also a count of how many non-zero
numbers you have seen.
B. Write a program that reads a single number and then prints
a line with this many * characters. For example:
How many *'s would
you like? 10
