Question

I am working on solving a mathematical problem.
What I am trying to do is to have an if statement that compares variable n to a set of variables i 1 through 10. Is there any way to do it in c++?
here is what I am trying to do:

 int smallPos(int n){
     if (n%for(int i=1;i<=10;i++)==0) {
        return n;
      }

This is obviously wrong but is any way to get around it?

Answer 1

What you want to do is this:

int smallPos(int n)
{
    for (int i = 1; i <= 10; ++i)
    {
        if (n % i != 0) // check if n % i == 0, if not, then we shouldn't return n.
        { 
            return -1; // or whatever you want to return when not ALL the remainders are 0.
        }
    }

    return n; // If we get here then all the remainders were 0s.
}
