Hey there guys, so I'm trying to make a fractions calculator. I did a research and I read that is easier to make a class but I'm not allowed to do that yet. I think my code isnt that wrong, probably some slightly error is escaping me.
When I run this program it just gets stucked after I put both fractions and the op symbol. Something wrong with my switch?



Thank you very much, hope you can help me :)

You chosen to withhold from us the definition of your reduceFracc() function, so you've limited our ability to help you. I assume you have a good reason for doing that.

I'd recommend you step through your code with a debugger, to identify exactly where it's getting stuck.

void reduceFracc(int &numerator, int &denominator)
{
	int *pNum;
	int *pDom;

	pNum = &numerator;
	pDom = &denominator;

	for (int i = numerator*denominator; i > 1; i--)
	{
		if (denominator%i == 0 && numerator%i == 0)
		{
			denominator = denominator / i;
			numerator = numerator / i;

		}
	}

}


This is my reduceFracc() function and as far as I know its working properly :)

Could you explain me how to work with debugger? Just 1 or 2 tips. It would be really helpful in the future.

Cheers
