C++ eliminating odd or even numbers

I'm doing an exercise where it is asking to eliminate any number divisible by 5 that ends up as a whole number. So instead of :

If (num == 5 || num == 10) 
    continue;

Is there some way to tell the computer if it is divisible by 5 don't output it or if it is odd or even don't output the number? Please try to leave answers at a novice level I am just starting to program.

Yes. A number is divisible by 5 with if the modulus, namely, operator% returns 0.

You can do:

if (n % 5 == 0) {
  //number is divisible by 5
}
else {
  //not divisible by 5
}

The modulus operator % gives you the remainder of a division, so you can just check if that is zero

num % 5 == 0

if (num % 5 == 0)
    continue;

Will only continue on 5, 10, 15...

bool isDivisibleBy5 = n % 5 == 0;

where n is your number. For odd numbers,

bool isOdd = n % 2; // evaluates to 0 if even, so false
