Problem Source: http://www.cskaoyan.com/viewthread.php?tid=244542pid=1593533page=1extra= #pid1593533 My answer:First of all, on the structure of the supplement, the domestic classic textbook-Tan Haoqiang's "C + + programming" clearly stated:1, in C language, the definition of the structure of the variable format: struct A;2, in C + +, the definition of the structure of the variable format: a A;In addition, C + + retained the style, that is, C + + can
Let's look at a few examples (1) struct{int x; int y;} Test1; Well, define the structure test1, test1.x and test1.y can be used in the statement. (2) struct test {int x; int y;} Test1; Well, define the structure test1, test1.x and test1.y can be used in the statement. Compared with 1, the province wrote Test (3) typedef
Today, when defining struct, we found that the typedef struct and struct have some differences: Structure is also a type of data. You can use Structure Variables. Therefore, like other types of variables, you must first define them when using structure variables.The general format for defining structure variables is:St

Typedef indicates the type definition. Typedef struct is convenient to use this struct.The specific difference is:If struct node {} is used to define the struct. When applying for a node variable, you need to write it like this, struct
