    bool functions

    ok. I am having a problem with a function that calls a boolean. Here is my code. any comments appreciated!


    bool showcomp(char isgameover);

    void showcomphand(bool isgameover)
    {
    cout<<"My hand is: ";
    if(!isgameover)
    {
    cout<<hiddencard<<" "<<endl;
    }
    for( int i = !isgameover; comphand[i] !=0; i++)
    {
    switch (comphand[i])
    {
    case 1: cout<<"A ";
    break;
    case 11: cout<<"J ";
    break;
    case 12: cout<<"Q ";
    break;
    case 13: cout<<"K ";
    break;
    default: cout<<comphand[i]<<" "<<endl;
    break;
    }
    }
    cout<<endl;
    }

    use code tags!
    what is the problem exactly?

    the if statement do look suspect tho..

    is isgameover an int?
    when last game is played does it really equal 0?

    didnt see rest of the code so just asking..
