    Mine wors in my compiler, but when I put the exact same code in the Hackerank compiler, it gives me the wrong answer. Very bizarre:

    class Student
{
    std::vector<int> scores{};

public:
    void input()
    {
        // If std::cin buffer has '\n', then clear the buffer
        if (std::cin.peek() == '\n') {
            std::cin.ignore(std::numeric_limits<std::streamsize>::max(), '\n');
        }

        std::string str;

        //read input and store it in a string "str", note that this includes the newline character '\n';
        std::getline(std::cin, str); //a way to remove the newline from the string

        std::stringstream iss( str );

        //convert the numbers on the string to an integers and store it as elements of vector str_int
        int score;
        while (iss >> score)
        {
            scores.emplace_back(score);
        }
    }

    int calculateTotalScore()
    {
        int total{0};
        for (const auto &num: scores)
        {
            total += num;
        }
        return total;
    }
};
