Why there is no output? Is there suppose to have Number=1,Number=2,Number=3...until 5?

Question

#include <iostream>
using namespace std;

int main()
{
int num = 1;
if (num=3){
num+=3;
}
else {
num= 1;
}
while (num < 6) {
cout << "Number: " << num << endl;
num++;
}

return 0;
}

Answer 1

you are setting it equal to (=)
instead of testing for equality (==)

... If num==3

Answer 2

Thank you! Oh that "else" is useless over here.
