Hey guys. I made a currency converter program and I was wondering what function I use to make it restart? I have it so that it asks if you want to quit or not, and if the person answers with either 'y' or 'yes', it will quit, but now I need the function so that it will restart if they enter 'n' or 'no'!

Thanks for the help, guys!

Um... I'm not that good at C programming (I'm just learning C), but my book had an example where you would have a "while" loop statement, and it would ask you to enter a number to proceed with the equation it solves, or press 0 to quit. So maybe you can use a "while" loop and have someone press "0" if they want to quit, or anything else to proceed.

Just an idea. I'm not especially good at this.

Use a do while loop that encases most of the program.

yeah, do a while statement that re-runs the program until the user answers no

while (userInput != y || userInput != Yes)
{
::call initial function::
}

Thanks but I'm quite new at this too...

What do you mean? :S

he's saying that you start the while statement in your main function, so that while userInput != y || userInput != yes, the program will continue executing until kingdom come

*edit* do you have your source?

Oh...nevermind all I had to do was main();

Lol thanks anyways guys.

int main();
{
//declare variables
//welcome message & other things you don't want repeated

do
{
//program that you want repeated
.
.
.

.

//ask if you want to repeat and store the answer in, oh lets say 'ans'

}
while(ans == y || ans == yes)

//all closing things

return 0;
}

Hopefully that helps. Ask more if you need it

I would suggest what bartender posted rather than calling main again. Your way recursively calls main, which wastes memory. The program is trivial so it doesn't really matter, but bartender's post is better coding practice
