typedef struct

struct and typedef structdivided into three pieces to tell:1 First://Note different in C and C + + to define a struct type in C, use a typedef:typedef struct STUDENT　　　　{int A;}stu;so when declaring a variable, you can: Stu stu1; (if there is no TypeDef, you must use

In the C language, define a struct to use a TypeDef, such as the following example code, stack sq; the stack is the alias of the struct Stack.If a typedef is not used, such as definingstruct Test1{int a;int b;int c;};Test1 t;//declaring variablesThe following statement will be an errorstruct.c:31:1: Error: must use '

Typedef is a key word in C language. It defines a new name for a data type. The data types here include internal data types (int, char, etc.) and Custom Data Types (struct, etc ). In programming, typedef is generally used for two purposes. One is to give a variable a new name that is easy to remember and clear, and the other is to simplify some complicated type d

(1) struct {int X; int y;} test1; good. The test1, test1.x, and test1.y structures are defined and can be used in the statement. (2) struct test {int X; int y;} test1; good. The test1, test1.x, and test1.y structures are defined and can be used in the statement. Compared with 1, test (3) typedef struct test {int X; int

Label: C structure struct typedefZookeeperThe code shows several types of struct in the past few days. The structure declaration is as follows:Struct book {String name;Int price;Int num;};The format of this structure definition structure variable is as follows:Struct book student;Struct book {String name;Int price;Int num;} Student;This form indicates that the pr

The first thing I think about is to go to MSDN to see what is sturct, although usually in use, but each use of the time is not clear what the difference between the two things, since Microsoft has MSDN, why we do not make good use of it, here is an excerpt from MSDN: The struct keyword defines a structure type and/or a variable of a structure type. A structure type is a user-defined composite type. It is composed of ' fields ' or ' members ' that can

Differences between typedef struct and struct Whether in C or C ++, typedef struct can be used to define a struct type, as shown below: Typedef

Struct mystruct { Int value; Const char * key; } Jstruct; Typedef struct mystruct2 { Int value; Const char * key; } Jarekstruct; Typedef is an alias jarekstruct for mystruct2, while jstruct is a mystruct object. The two definition methods are also different in use: St
