static const

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

In the linear table, FIFO is called the queue, advanced out of the call stack. Queues are commonly used in BFS, and when the recursive hierarchy of functions is too high, the recursive process needs to be manually implemented, and a "manual stack"

This note is summarized from a code view. In general, when programming with C, we are used to defining a numeric constant in our code using the macro definition in C: #define MY_CONST 7 When developing a project in C + +, there is

Let's take a look at an example: #include　 template　 class　Fibnacci { public: 　　　　static　const　int　value　=　Fibnacci::value　+　Fibnacci::value; }; template　<> class　Fibnacci { public: 　　　　static　const　int　value　=　0; }; template　<> class　Fibnacci {

First, preprocessing commands he is not a constant!!!! Let's look at a piece of code #define @ "Avatar" if (false) { #define AVATAR @ " NSLog"} (Avatar); How much does this code output, we define "avatar" for 60, and then redefine

Class A { Public static const int CI; }; const int A::CI = 10; int main () { cout return 0; } Compile with no problem, run will error. , because CI is undefined, memory is not allocated, and object CI is not established as an entity. "Note" for
