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

You are asking the user to input 5 int values and after each input you add it to the total variable so eventually you're printing the total var after you increment each input to the total.

for example: 5 4 7 6 3

total += 5. num= 1
total += 4. num= 2
total += 7. num= 3
total += 6. num= 4
total += 3. num= 5

as you can see num is five so it exits the while loop and prints on the screen the sum of the inputs (25)
