C++ ? operator with continue operator in for loop

I have a method which looks like this:

bool Perfect(int num) {
    int sum = 0;
    for (int i = 1; i < num; i++)
    {
        num%i == 0 ? sum += i : continue;
    }
    return sum == num ? true : false;
}

I'm trying to combine here ? operator with continue operator...

So logically if the statement here is false in this line: 

num%i == 0 ? sum += i : continue;

I will just skip the iteration or do nothing?

If I do it like this the compiler reports an error like:

expected an expression

And in case like this:

num%i == 0 ? sum += i

It says: 

Expected a ':'

Is there any way to use continue with ? operator or just simply avoid false case somehow ???

Solution 
  • bool Perfect(int num) {
    int sum = 0;
    for (int i = 1; i < num; i++)
    {
        if(num % i == 0)
         sum += i;
    }
    return sum == num;
}

    Use an if statement. No need of continue since you have no other statement after sum += i.
