- 1.结构体嵌套结构体
struct student
{
?? ?string name;
?? ?int age;
?? ?int score;
?? ?
};
struct teacher
{
?? ?int number;
?? ?string name;
?? ?int age;
?? ?struct student stu;
};
void print_struct(struct student* p) {
?? ?cout << "学生姓名：" << p->name << endl
?? ??? ?<< "学生分数：" << p->score << endl;
}
teacher t;
?? ?t.name="老王";
?? ?t.age = 28;
?? ?t.number = 1;
?? ?t.stu.name = "小王";
?? ?t.stu.age = 10;
?? ?t.stu.score = 100;
?? ?cout << "老师的姓名：" << t.name << endl
?? ??? ?<< "老师的年龄： " << t.age << endl
?? ??? ?<< "老师的学生： " << t.stu.name << endl;
?? ?print_struct(&t.stu);//地址传入
- 2.获取字符串的第几个字符
#include <string>
string nameSeed="ABCDE";
void allocate(struct Teacher tArray[],int len){
? ? ? ? for(int i =0;i<len;i++){
? ? ? ? ? ? ? ? tArray[i].name = "Teacher_";
? ? ? ? ? ? ? ? tArray[i].name += nameSeed[i];//直接字符串nameSeed[i]，就行
????????}
}
- 3.案例：根据结构体的年龄，使用冒泡排序：
#include <iostream>
using namespace std;
#include <string>
struct Hero
{
?? ?string name;
?? ?int age;
?? ?string sex;
};
void sort_hero(struct Hero hero[],int len) {
?? ?struct Hero h1;
?? ?for (int i = 0;i<len-1;i++) {
?? ??? ?for (int j = 0;j<len-1-i;j++) {
?? ??? ??? ?if (hero[j].age>hero[j+1].age) {
?? ??? ??? ??? ?h1 = hero[j];
?? ??? ??? ??? ?hero[j] = hero[j + 1];
?? ??? ??? ??? ?hero[j + 1] = h1;
?? ??? ??? ?}
?? ??? ?}
?? ?}
}
void print_info(struct Hero hero[], int len) {
?? ?for (int i = 0;i<len;i++) {
?? ??? ?cout << "英雄人物：" << hero[i].name
?? ??? ??? ?<< " 英雄年龄：" << hero[i].age
?? ??? ??? ?<< " 英雄性别：" << hero[i].sex << endl;
?? ?}
}
int main() {
?? ?struct Hero hero[5] = {
?? ??? ?{"刘备",23,"男"},
?? ??? ?{"关羽",22,"男"},
?? ??? ?{"张飞",20,"男"},
?? ??? ?{"赵云",21,"男"},
?? ??? ?{"貂蝉",19,"女"}
?? ?};
?? ?int len = sizeof(hero) / sizeof(hero[0]);
?? ?sort_hero(hero, len);
?? ?print_info(hero,len);
?? ?system("pause");
?? ?return 0;
}
- 4.c++清屏操作
system("pause");
system("cls");
?
