    help needed for my connect four programme.

    hi there. katy here.
    I am doing a "Connect 4" program for my assignment and i've done the main part, which I should not change (my lecturer told me not to). .can anyone help me to convert this function below to suit my program??i need my program to have a verticalwin/horizontalwin and a diagonalwin function. and also when all the tiles is full,i want my program to give an output such as "the game is a tie".please help me.i'm new here.so forgive me if i'm wrong.
    the function that i need modified is:

    Code:
    bool check(int a, int b)
    {
        int vertical = 1;//(|)
        int horizontal = 1;//(-)
        int diagonal1 = 1;//(\)
        int diagonal2 = 1;//(/)
        char player = place[a][b];
        int i;//vertical
        int ii;//horizontal
    
        //check for vertical(|)
        for(i = a +1;place[i][b] == player && i <= 5;i++,vertical++);//Check down
        for(i = a -1;place[i][b] == player && i >= 0;i--,vertical++);//Check up
        if(vertical >= 4)return true;
    
        //check for horizontal(-)
        for(ii = b -1;place[a][ii] == player && ii >= 0;ii--,horizontal++);//Check left
        for(ii = b +1;place[a][ii] == player && ii <= 6;ii++,horizontal++);//Check right
        if(horizontal >= 4) return true;
    
        //check for diagonal 1 (\)
        for(i = a -1, ii= b -1;place[i][ii] == player && i>=0 && ii >=0; diagonal1 ++, i --, ii --);//up and left
        for(i = a +1, ii = b+1;place[i][ii] == player && i<=5 && ii <=6;diagonal1 ++, i ++, ii ++);//down and right
        if(diagonal1 >= 4) return true;
    
        //check for diagonal 2(/)
        for(i = a -1, ii= b +1;place[i][ii] == player && i>=0 && ii <= 6; diagonal2 ++, i --, ii ++);//up and right
        for(i = a +1, ii= b -1;place[i][ii] == player && i<=5 && ii >=0; diagonal2 ++, i ++, ii --);//up and left
        if(diagonal2 >= 4) return true;
    
        return false;
    }
    i need it to suit my current programme.please help.

    where did that function you showed come from? Why if you could write the rest have you not posted an attempt of your own at writing the required function? What exactly do you have trouble with, because nobody is going to just offer a complete piece of work for you to appropriate. sorry- that costs money ;->

    You could think about it and do it yourself, and learn something.

    You should post what you have attempted as far as refactoring this function goes, but really i would abandon and code something that is more in line with your own work, it may be you are trying to fit a square peg into a round hole (sure thats a pun here...) and actually making more work for yourself trying to crowbar in the code your friend gave you. especially if you are having difficulty understanding what she has given you anyhow.

    Also consider if its the best way to do it that she has shown you? Just because she managed to get it working in her project does not mean it will translate neatly to your version.

    Your "fren" at StackOverflow? Which may have originated here?

    Lies, lies, lies. Stop trying to get everyone to do your homework for you. If you don't want to program, then drop out of your class and go study something else.

    I like the technique of using a female name and a random human female's picture as an avatar. Nice touch.
