struct和typedef struct用法

typedef struct Student{

int score;

}Stu;       //Stu是结构类型，是Student的别名，Stu==struct Student

Stu stu1;   //stu1是一个Stu结构类型的变量

struct Student{

int score;

};    

struct Student  stu1; //stu1是一个Student结构类型的变量，只能这样定义

typedef struct
{

int score;

}Stu; //Stu是结构类型

Stu stu1;     //这里只能这样定义一个新的变量

struct Student
{

int score;

};　　

Student stu1;//比C语言少一个struct

struct Student1
{

int score;

}stu1; //stu1是一个变量


typedef   struct   Student2   
{   

int   score;   

}stu2; //stu2是一个结构类型=struct Student2，等同于c语言

struct Student
{

int score;

}stu1; //stu1是一个变量

Student stu2，stu3;
