代码

#include <iostream>
using namespace std;
#include <string>
#include <ctime>

//学生的结构体
struct Student
{
	string sName;
	int score;
};
//老师的结构体定义
struct Teacher
{
	string tName;
	struct Student sArray[5];
};

//给老师和学生赋值的函数
void allocateSpace(struct Teacher tArray[],int len)
{
	string nameSeed = "ABCDE";
	//给老师赋值
	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所带的学生赋值
		for (int j = 0; j < 5; j++)
		{
			tArray[i].sArray[j].sName = "Stduent_";
			tArray[i].sArray[j].sName += nameSeed[j];

			int random = rand() % 61 + 40;//0+40-60+40
			tArray[i].sArray[j].score = random;
		}
	}
}

//打印所有信息
void printInfo(struct Teacher tArray[], int len)
{
	for (int i = 0; i < len; i++)
	{
		cout << "老师姓名:" << tArray[i].tName << endl;
		for (int j = 0; j < 5; j++)

			cout << "\t学生姓名:" << tArray[i].sArray[j].sName
				<< " 学生分数:" << tArray[i].sArray[j].score << endl;
		}
	}
}

int main()
{
	//随机数种子
	srand((unsigned int)time(NULL));

	//创建3名老师的数组
	struct Teacher tArray[3];

	//通过函数给3名老师的信息赋值,并给老师带的学生信息赋值
	int len = sizeof(tArray) / sizeof(tArray[0]);
	allocateSpace(tArray, len);

	//打印所有老师及学生的信息
	printInfo(tArray,len);
