The standard threshold for this complexity is 10 points, so if you have a function with higher complexion than that, you should try to reduce it.It will begin by adding 1 point for the function declaration, after that it will add 1 point for every if, while, for and case. Introduction to Cyclomatic Complexity. How do you say “Me slapping him.” in French? I would recommend the following tools: UPDATE: I strongly recommend looking at CppDepend (commercial), one stop solution for all kinds of metric.
