Efficient C++ Performance Programming Techniques

Obsolete Code

This is another one of those tips that sounds silly but actually happens in practice quite often. We are talking about code that no longer serves a purpose but still remains on the execution path. This is not likely to happen on a school programming assignment or a small prototype. It happens on large-scale programming efforts. The requirements that drive a software implementation are a moving target, tending to evolve from one release to the next. New features are added and support for old features may be dropped. The implementation itself keeps shifting underneath your feet with bug fixes and enhancements. This constant movement of requirements and implementation creates bubbles of dead (never executed) and obsolete (executed ...
