C++项目-结构体案例1

项目要求：3名老师，每名老师带5个学生

#include 
using namespace std;

//学生
struct student {
	string s_name;
	int score;
};

//教师
struct teacher {
	string t_name;
	struct student s_Arr[5];
};

//赋值函数
void allocateSpace(struct teacher t_Arr[], int len) {
	string nameSeed = "ABCDE";

	//给老师赋值
	for (int i = 0; i < len; i++) {
		t_Arr[i].t_name = "Teacher_";
		t_Arr[i].t_name += nameSeed[i];

		//给学生赋值
		for (int j = 0; j < 5; j++) {
			t_Arr[i].s_Arr[j].s_name = "Student_";
			t_Arr[i].s_Arr[j].s_name += nameSeed[j];

			int random = rand() % 61 + 40;//40~100
			t_Arr[i].s_Arr[j].score = random;
		}
	}
}

//打印函数
void printInfo(struct teacher t_Arr[], int len) {
	for (int i = 0; i < len; i++) {
		cout << "老师的姓名：" << t_Arr[i].t_name << endl;
		for (int j = 0; j < 5; j++) {
			cout << t_Arr[i].s_Arr[j].s_name << "的成绩为：" << t_Arr[i].s_Arr[j].score << endl;
		}
	}
}
int main() {
	//随机数种子
	srand((unsigned int)time(NULL));   
	//创建三名老师数组
	struct teacher t_Arr[3];
	int len = sizeof(t_Arr) / sizeof(t_Arr[0]);
	//通过函数赋值
	allocateSpace(t_Arr, len);
	//打印信息
	printInfo(t_Arr, len);
	system("pause");
	return 0;
