My program keeps on crashing saying I'm dividing by zero even though I have a check to make sure that I'm not dividing by zero, why?

DWORD last_time = 0, elapsed = 0;
int FPS = 0;

//

while(running == true)
{
	elapsed = GetTickCount() - last_time;
	if(elapsed == 0) elapsed == 1;
	last_time = GetTickCount();

	//

	FPS = 1000/elapsed;
}

*** Source Snippet Removed ***

You're using the equals operator for setting elapsed instead of the assignment operator.

Your Code:
elapsed == 1;

Right Code:
elapsed = 1;

Omg, I feel so stupid right now >.<

Thank you.

int x = 0;if (x == 0) x == 1;

When I compile that, I get "warning: statement has no effect". Crank up your warning levels!

Yup do yourself a favor and let the compiler do more of the work for you [wink]
