Sum a column

Read first Task 36

Loops plus a total field answer money questions.

Definition and example

Sum a column is the focus of this lesson. Loops plus a total field answer money questions. The task asks you to apply that idea in a small example: What answers 'how much money in total?'. Before you run the code, predict what should happen. Then Inspect the program output and the compiler message if it fails and compare it with your prediction. If the result differs, change one relevant line and run it again. Testing one change at a time makes the cause of a result easier to understand.

int main() {
    vector<int> fees{9000, 11667, 4000};

    for (int fee : fees) {
        total = total + fee;
