Thread: Determining if a number has a remainder?

How could I do this in C? Knowing the remainder would be cool too.

If no one can think of a way of this, how about how can I find out if a number is even or even prime?

:-/

Yes, % will work, but here's a fun way:

Code:

int divide( int toDivide, int divideBy )
{
   int x=0;
   x = toDivide / divideBy;
   return ( toDivide == (divideBy * x) );
}

That should do something like:

Code:

printf("6 / 3 = 2, is there a remainder? %s.", divide( 6,3 ) ? "No" : "Yes" );

Alternatly, you could just make that return the remainder:

Code:

int divide( int toDivide, int divideBy )
{
   int x=0;
   x = toDivide / divideBy;
   return (toDivide-(x*divideBy));
}

Quzah.

this does an integer division and returns the remainder.

I think you can work the rest out!

Hey thanks I had forgotten about the modulus operator!

I need to refresh my C skills.. hehe
