Can you explain 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;
num++;
}
cout << total << endl;

return 0;
}

Answer 1

Summation of 5 numbers that we input each time in loop.
The sum will be stored in variable total.

Answer 2

while num - - > 1 and its less than 5 which is true

cin>>number; - - >take an input

total+=number add the inputed number to total, which can also be re-written as total=total + number;

num++; increases thef value of num, which is previously 1 to 2, num++ is the same as num=num+1;

when num is greater than 5, the loop stop and go to the next, which is cout<< total << endl;
the value stored in total will then be printed out
