Medium-Sized Slugs

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.
