Your first C++ project

Read first Task 50

Put the pieces together: data, loop, function, report.

Definition and example

Your first C++ project is the focus of this lesson. Put the pieces together: data, loop, function, report. The task asks you to apply that idea in a small example: What does a good first C++ project include. 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.

// TASK your-first-c-project-10: What does a good first C++ project include?
// STEPS: Read the explanation. Change one relevant line at a time, then run the code and compare the result with the check on the right.
#include <iostream>
#include <string>
#include <vector>
using namespace std;

int total_of(vector<int> fees) {
    int total = 0;
    for (int fee : fees) {
        total = total + fee;
    }
    return total;
}

int main() {
    vector<int> fees{9000, 11667, 15000};
    // TODO: produce the required output for this task.
    cout << "Expected: Rs " << total_of(fees) << endl;
    return 0;
}
