Ok,
But in this line:
while (toupper(anotherTable) == 0);
you are checking if the upper case value of what the user entered is 0.
Try:
while (toUpper(anotherTable) == 'Y');
note the single quotes around the character Y.

I wanted the user to type Y if they wanted another multiplication table, and
n if they wanted the program to quit. So how can I implement that? I thought
the entries of the characters Y or N would need the using std::string? So
confused!

Have a look at the while condition on the last line before the return
statement. What do you expect to have been typed in answer to the
preceding question?

Hi all,
After working on this program for four hours total, I finally got all the
syntax errors out and the program runs.
It's a simple program that multiplies a number from 1 to 10, then displays
the results. It asks the user to enter the number they want multiplied,
then it does the multiples. After it displays the results to the screen,
it is supposed to ask the user if they want another multiplication table
displayed. If the user presses y, it should start all over again, and if
they press n, the program should exit.
However, every time I run the program, it exits on me no matter what
answer I give it. If I answer y, it exits. Can somebody take a look at
this code and tell me what I'm doing wrong?
Thanks for any help.
Jes
