结构体案例1

#include <iostream>

#include <ctime>//利用时间实现随机

using namespace std;

struct student {

string name;

int age;

float score;

};

struct teacher {

string Tname;

struct student Sarray[5];

};

void AssignName(struct teacher Tarray[], int len) {//给老师和学生赋值的函数

string NameSeed = "ABCDE";

//给老师开始赋值

for (int i = 0; i < len; i++) {

Tarray[i].Tname = "Teacher_";

Tarray[i].Tname += NameSeed[i];

//通过循环给每名老师带的学生赋值

for (int j = 0; j < 5;j++) {

Tarray[i].Sarray[j].name = "student_";

Tarray[i].Sarray[j].name += NameSeed[j];

int random = rand() % 61 + 40;//实现60-100随机生成

Tarray[i].Sarray[j].score = random;

Tarray[i].Sarray[j].age = 18;

  

}

}

}

//打印函数

void Print(struct teacher Tarray[], int len) {
