Question

All, quick and easy one here…

I’m writing an Evaluate function that runs through a bunch of other bool functions. Right now, I’m basically doing an if, else if loop (seen below). Any suggestions on another way of doing this??? I’m assuming I could do this with a switch but have never used them before like this.

int i = 78;

if (isPrime(i))
{
     cout <<"is prime" << endl;
     return;
}

else if (ismultipleOf23(i))
{
    cout <<"is a multiple of 23" << endl;
    return;
}

else if (isEven(i))
{
    cout <<"is Even" << endl;
    return;
}

else if (isOdd(i))
{
    cout <<"is Odd" << endl;
    return;
}

You can’t use a switch because the labels have to be constant.

What you are doing is the correct way.
