Hi,
If I remember right, you would use while loop and conditional statements
inside the loop until the correct values are entered. A pseudo code might
be:
while (the numbers are not between 1 and 3) // Try using "&&" operator.
{
/* The conditional statements to check the user input.
If it is not the value that the program is looking for, display the error
and prompt the user to enter the values again.
If it is the value that the program is looking for, exit the loop. */
}
Cheers,
Joseph

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
