5. 结构体

5.1 定义

struct student
 {
     string name;
     int age;
     int score;
 }s3;
 int main()
 {
     student s1;
     student s2 = {"李四", 19, 80};
 }

5.2 结构体数组

struct 结构体名 数组名[元素个数] = {{}, {}, {}, {}, {}};

5.3 结构体指针

student s = { "李四", 19, 80 };
student* p = &s;
cout << p->age << endl;
cout << p->name << endl;
cout << p->score << endl;

5.4 结构体嵌套结构体

struct teacher
 {
     int id;
     string name;
     int age;
     struct student stu;
 }

5.5 结构体做函数参数

5.6 const

const防止误操作

void printStu(const student *s)
 {
     cout<<s->name<<endl;
 }
