In general, the initialization of static members of C + + classes is not difficult to understand, but refers to the "in-class initialization" of C + + static members that is confusing.Let's look at the following code:1 //example.h2#include 3#include

when programming in C language, it is very attractive to find details. A more detailed look at a bit about the knowledge of include, found a few things:1.include and include "header file name"such as:include and include "Stdio.h"The former (using <>)
