I know it's a bit late reply, but incase someone else stumbles upon this thread I'd like them to know there're other ways to do it as well, one way I prefer is like this:

Code:

int main(){ // We want to initiate the values for safety precautions int input = -1, sum = 0; // while we're recieving inputs and the input is not equal to 0 while (cin >> input && input != 0){ // same as sum = sum+input sum += input; } cout << sum; return 0; }
