This may be why I'm not going more in depth regarding this; it is possible
but to much low level programmation.

Let's not forget:
- C++:
        A high-level programming language developed by Bjarne Stroustrup at
Bell Labs. C++ adds object-oriented features to its predecessor, C.

- C:
        A high-level programming language developed by Dennis Ritchie at
Bell Labs in the mid 1970s. Although originally designed as a systems
programming language, C has proved to be a powerful and flexible language
that can be used for a variety of applications, from business programs to
engineering. C is a particularly popular language for personal computer
programmers because it is relatively small -- it requires less memory than
other languages.

    Thus C++ should require less memory than other languages.
