카타 8급 Can we divide it?

C++

bool isDivideBy(int number, int a, int b)
{
  return (a != 0) && (b != 0) && (number % a == 0) && (number % b == 0);
}

bool isDivideBy(int number, int a, int b)
{
  return ( number%a == 0 && number%b == 0 );
}

bool isDivideBy(int number, int a, int b)
{
  return !(number%a) && !(number%b);
}
