    Well you pretty much have to throw it away and read MSDN on how to use the serial port using the Win32 API.

    You can save all the code which deals with data once it's in memory.

    That would imply that you have more than true/false at some level.

    Because

    Having a function called 'get' which returns nothing is just weird.

    And just pushing the infinite recursion out of main doesn't really make much progress.

    So change the format string

    or

    int numbers[49];
    for ( int = 0 ; i < 49 ; i++ ) numbers[i] = i+1;


    vs this, which wastes element 0 of the array.
