What function does 'num++' perform in WHILE LOOP ?

Question

#include <iostream>
using namespace std;

int main()
{
int num=1;
int number;
int total=0;

while (num <= 6) {
cin >> number;
cout << total << endl;
total += number;
num++;
}
return 0;
}

Answer 1

MATTHEW CHRISTOPHER , incrementing variable num, if the variable is not incremented the loop never stops as the condition num <= 6, will be always true.
