    Help! (Beginner)

    Hello guys,

    I've got a Darts program at the moment and it calculates how many throws were needed to go from 301 to 0.

    I need to work out how to calculate the average of game frequency (how many games ended in 7 darts, how many games ended in 8 darts).

    I've got my game in a for loop so I can make it play 100 times I just don't know how to make it calculate the frequency averages!

    Thanks in advance

    Valdo!

    You could have an int array initialized to zero of a size big enough to hold the maximum number of darts that will ever be thrown. Then after each game, increment the element corresponding to the number of darts it took.
    Code:
    int numDarts[20] = { 0 };
    
    for (game = 1; game <= 100; game++) {
        // play the game; let's say that nDarts has the number of darts it took
    
        if (nDarts >= 20)
            cout << "numDarts array overflowed: " << game << ", " << nDarts << "\n";
        else
            numDarts[nDarts]++;
    }
    
    // print out numDarts array
    Since this is C++, you may want to use a vector instead.

    I can't see your while loop from here, but I suspect that it corresponds to the for loop in my example.

    It can't be that long (even a few hundred lines is not too much). Just post it here. Put it in between code tags like this:

    [code]
    put your code here
