    Instead of
    Code:
    void main()
    put
    Code:
    int main()
    delay() is not declared in headers that you included, so find the appropriate header and include it.

    If you are using delay() to make the program wait, you can use sleep() to achieve the same
    result. It is declared in the windows.h header file.

    Oh, and like Karas said, main returns an int, and dos.h is a very dated header. Turbo C++ is
    an old compiiler nowdays, most of the functions it incorperates will nor work on todays more modern compilers. Read the documentation in the help files on DevC++ to find out more information
