Can any one please explain me this C++ code ......?

Question

#include <iostream>
using namespace std;

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

while (num <= 5) {
cin >> number;
total += number;
}
cout << total << endl;

return 0;
}

Answer 1

There is an issue with your loop. The loop will run infinite as the condition will remain true. So add num++; in the loop so that the loop stops executing after the condition is false.

Answer 2

wait no no wait.

++num

is what thou needeth. Looketh. The for loops gonna run (like FOREST GUMP). Can’t have it run. Can’t have it misbehave like that. Give a smack. Give it some DSCIPLINE.
