Could someone explain me this with numbers please

Question

#include <iostream>
using namespace std;

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

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

return 0;
}

Answer 1

This program asks for any number.

Num is initial 1, which is less than 5 so the program will enter the while-loop. Num is a counter, that counts the number of iterations.

In the while-loop, the program asks for a number, add the number to a variable total. And increases the "num"-variable, which is not the same as "number"-variable.

So this program asks 5 times a number and calculates the total of the given numbers.

1 + 2 + 3 + 4 + 5= 10
100 + 100 + 100 + 100 + 100 = 500

(Please put c++ in your tags)
