sigfpe error

I keep getting SIGFPE error when i try to run my program. 
Why so? This is the easiest runtime error to debug -
it is a floating point error. It is virtually always
caused by a division by 0, so check any divisions or 
modulo operations in your code carefully.

This error is a floating point error, occurs usually when you try to divide 
something by 0. Check the division and modulo operation in your code.
