This is my latest homework, could anyone help me find out the error in my isPrime() function. Also how do I set this up to print my return values, for example for isOdd() true = odd, so how would I get it to print Odd? I just need some direction, using functions and returns is confusing me.

Thanks for any input I'm a complete noob.
