A while loop. this is a good example of what that loop is good for.
Prompt for input;
receive input;
while input is invalid {
display error;
accept new input;
}
.
.
.
continue processing;
Hope this pseudo code helps.

Subject: Implimenting prompts in program for reinput from user?
Say I want a user to enter a number from 1 to 3, but they enter something
else, like 4, or the letter v, or whatever. How would I tell the program to
display an error message to the user using cout, then return them to the
initial prompt?
Thanks.
Jes
