    My stupid strings aren't working...

    Alrighty, I know a ton about strings from Game Maker. But I don't know how long a string[256] is. How many letters can fit in that?

    if it is:
    Code:
    char string[256];
    It can hold 255 characters and a null character.

    Code:
        {
            char answera[1];
            char answerb[1];
            char answerc[1];
            cout<<"Here is the test...\n\n\n";
            getch();
            cout<<"question 1...\n\nWhat does blah blah mean?\n\nA. Start blah blah not importent.\nB. or answer 2.\n";
            cin.getline(answera, 1, '\n');
            cout<<"your answer was:"<<endl<<answera;
            getch();
            mainmenu=1;

    The fact that you are using a value of 1 for the array size. If it is to be a string then it has to have a null terminating character which means you have no room for the actual answer.

    If you just want a character then just use a char instead of trying to hack it with a string.

    Well you weren't using c++ strings you were using c strings.

    C string = a null terminated array of characters
    C++ string = a class found in <string>
