    >void main()
    int main()

    >if(buffer == "hallo")
    This isn't doing what you think it is. To compare C-style strings you need to use strcmp:
    Code:
    if ( strcmp ( buffer, "hallo" ) == 0 )
    My best code is written with the delete key.

    Code:
    char b;
    ...
    cin.get(b);
    that's just a waste of a byte... you can just use:
    Code:
    cin.get();
    at the end of the program to do the same thing

    Read this.

    >void main()
    While you're at it, read this too.
    My best code is written with the delete key.

    Just wanted to get you to know you should use the standard template library.

    #include <iostream.h>
    #include <string.h>
    #include <stdlib.h>


    instead use these

    #include <iostream>
    #include <cstring>
    #include <cstdlib>

    Good luck.
