C语言中的结构体

1 struct student
2 {
3    int id; 
4    char name[10];
5 
6 };

1 struct student 
2 {
3     int id;
4     char name[10];
5 } mike,lily; //直接定义两个结构体变量

1 student mike ={123，{‘m‘,‘i‘,‘k‘,‘e‘}};//定义变量并初始化
2 mike.id = 20130000+ mike.id //使用
3 for(int i = 0; mike.name[i] != ‘\0‘; i++)
4     mike.name[i]= toupper(mike.name[i]);
5 cout<<"ID: "<<mike.id<<"name: "<<mike.name<<endl;//

1 student mike ={123，{‘m‘,‘i‘,‘k‘,‘e‘}};
2 student lily;
3 lily = mike;//可以直接赋值，对应的变量也赋值

student mike={123,{‘m‘,‘i‘,‘k‘,‘e‘}};
student *ps = &mike; 
cout<<"ID: "<<(*ps).id<<"name: " <<(*ps).name<<endl;
cout<<"ID:"<<ps->id<<"name: "<<ps->name<<endl;

1 struct student 
2 {
3     int id;
4     char name[10];
5 } stu[10];
