Averaging code

This is a discussion on Averaging code within the C++ Programming forums, part of the General Programming Boards category; using accumulate and vectors is pretty neat also: Code: int num; vector<int> nums; while (cin >> num ) nums.push_back(num); double ...

    Code:
    int num;
    vector<int> nums;
    
    while (cin >> num ) nums.push_back(num);
    
    double avg = accumulate( nums.begin(), nums.end(), 0.0 ) / nums.size();

    It is pretty much what Neo1 suggested, and just as wasteful if the only thing needed is to compute the arithmetic mean.

If they do, I ask them to find the smallest example that exhibits the problem and send me that. Mostly, they then find the error themselves. "Finding the smallest program that demonstrates the error" is a powerful debugging tool.

    If i needed to find the mean, I wouldn't have used that code...

    just something interesting to learn about.
