conversion from double to float in c++

Question

I am new to programming. Here is part of my assignment, which requires using pass-by-reference. After I compile it and type in the values for win, draw and loss respectively,it returns me nothing. I don't know whether it is due to the problem in calling the function or the floating point.

void Cfunction(int win, int draw, int loss, float& point)

{
point = win * 2.5f + draw * 1 + loss * 0;
}

int main(void)
    {
        int win, draw, loss;
        float point;
        cout << "Please input the game record in the following order: win draw loss " << endl;
        cin >> win >> draw >> loss;

        Cfunction(win, draw, loss, point);
        cout << "The total score for the team is " << point << endl;

    }

Answer 1

Look good to me.

You could verify that your cin >> ... has finished by adding a cout << "calculatin total score...." << std::endl; .

(Note: std::cin >> wins has the wins variable passed by reference, too :))

Indeed, as @David Hefferman suggested, learn to use the debugger. Will save you a huge amount of time in the (very near) future.

Answer 2

Looks fine to me too. You do know that you have to add the numbers one by one on their own lines, eg 5 , 3 , 4 ?
