C++ provides 'illusions' (simple/fast/elegant..), you need to know the low level,
hardware events to harness it, or there are 'surprises'.

All programming have to be converted to machine codes. Human abstraction or 
ideal has no position in CPU's eye (so far, no computing model can surpass
Turing Machine). Some languages can simply its programming model, but not C++.

Doing so (making C++ high level language) might be possible, but not in the
programs you have shown. Your code is immature.
