There are more examples of crappy than good C++ out there. There
are tons of litterature on how to write crappy C++. And most
programmers do not have the skill or knowledge to write good C++.
My biggest issue with C++ is the variability of skills among
programmers. It will result in code that are:
- unncessesary complex
- ugly looking
- difficult to understand
- verbose and long
- full of subtile errors
- impossible to debug
- impossible to maintain
- not scalable with hardware
- dependent on one particular compiler
It is easier to achive this with C++ than C. But it is also
easier to avoid. Double-edged sword.
It will take more than guidelines.
