    fgets is not guaranteed to write a '\0' byte to the buffer, so strlen is not guaranteed to work. Hence this line:



    message[sizeof(message)-1] = '\0'; // Ensure '\0' termination.

    The label should be local to a function. It does not have a type, it is just a label. e.g.




    int my_function()

    You can create a label and use goto to jump to it. Some consider this bad style, but sometimes it is very useful.

    You could start with this simple organization and then modify it as you see fit:
