Improving Program Performance

You can improve the performance of C++ functions by writing those functions in a manner that helps the compiler do a better job of optimizing them. Many books have been written on software performance in general and C++ in particular. Rather than repeat such valuable information, this chapter discusses only those performance strategies that strongly affect the C++ compiler.
