C++师生成绩结构体嵌套

C++师生成绩结构体嵌套

 创建一个结构体，输出一个具有老师姓名，以及每个老师所带有学生的姓名和分数的结构体嵌套表示

struct student
{
	string name;
	int score;
};
struct teacher 
{
	string name;
	struct student arr1[5];
};
//赋值函数
void list(struct teacher arr[],int len,int len1)
{
	string name_ = "ABCDE";
	srand(unsigned int(time(NULL)));
	for (int i = 0;i < len;i++)
	{
		arr[i].name = "teacher_";
		arr[i].name += name_[i];
		for (int j = 0;j < len1;j++)
		{
			int score = rand() % 61 + 40;//随机数成绩在40-100之间
			arr[i].arr1[j].name = "student_";
			arr[i].arr1[j].name += name_[j];
			arr[i].arr1[j].score = score;
		}		
	}
}
//成绩打印函数
void print(struct teacher arr[], int len, int len1)
{
	for (int i = 0;i < len;i++)
	{
		cout << "老师姓名" << arr[i].name << endl;
		for (int j = 0;j < len1;j++)
		{
			cout << "t学生姓名_" << arr[i].arr1[j].name ;
			cout << "t学生成绩_" << arr[i].arr1[j].score << endl;
		}
	}
}
int main()
{
	struct teacher arr[3];
	struct student arr1[5];
	int len = sizeof(arr) / sizeof(arr[0]);
	int len1 = sizeof(arr1) / sizeof(arr1[0]);
	list(arr,len,len1);//老师学生成绩赋值
	print(arr, len, len1);//成绩打印
	return 0;
}
