    Chars

    I have a problem. I isolated it to two lines.

    Code:
    char *aMenuChoice;
    cin>>aMenuChoice;
    My problem, a runtime error. It is- The variable 'aMenuChoice' is being used without being defined.

    And we know it is.

    and then later I get this when I enter something and hit the key enter:
    Unhandled exception at 0x0041441f in Classes.exe: 0xC0000005: Access violation writing location 0xcccccccc.

    What's my problem?

    your variable is declared as a pointer
    and it is pointing to un-allocated memory...

    this is the thing that crashes your program

    it must be either

    char choise;
    cin>>choise;

    OR
    char *choise = new char[200];//string
    cin>> choise; //assign something to the string
