The editor already contains a starting point. Change it until every check passes — the Next task button unlocks when it does.
What you start with
#include <iostream>
#include <vector>
using namespace std;
int total(const vector<int>& marks) {
int sum = 0;
for (int mark : marks) {
sum += mark;
}
return sum;
}
int main() {
vector<int> marks = {850, 920, 780, 640};
cout << "Total: " << total(marks) << endl;
cout << "Average: " << total(marks) / marks.size() << endl;
return 0;
