Medium-Sized Slugs

There are a lot more examples of possible inefficiencies in C++ coding. Some of the types of errors that are “medium-sized” slugs include:

Automatic array initializations with constant data.
Loop test function calls (ie. expensive loop conditional tests).
Member initializations in the constructor body (they should be in the initializer lists).
Program startup hidden initializations (global or static object constructors).
Small non-inline functions called frequently.
Busy wait loops.
Unnecessary code inside loops.
C++ classes wrapping simple data types (e.g. overuse of “smart pointers” or “smart integer” classes).
Overuse of standard string concatenation operations.
Recursion is almost always a slug.
