  • 实现:结构体案例

    案例1描述:

    学校正在做毕设项目,每名老师带领5个学生,总共有3名老师,需求如下

    设计学生和老师的结构体,其中在老师的结构体中,有老师姓名和一个存放5名学生的数组作为成员

    学生的成员有姓名、考试分数,创建数组存放3名老师,通过函数给每个老师及所带的学生赋值

    最终打印出老师数据以及老师所带的学生数据。

    #include<iostream>
    #include<string>
    #include<ctime>
    using namespace std;
    
    
    struct student {
    	string name;
    	int score;
    };
    
    struct teacher {
    	string name;
    	struct student stu[5];
    };
    
    void to_catch(struct teacher t[], int len) {
    	string nameSeed = "ABCDE";
    	for (int i = 0; i < len; i++) {
    		t[i].name = "Teacher_";
    		t[i].name += nameSeed[i];
    		for (int j = 0; j < 5; j++) {
    			t[i].stu[j].name = "student_";
    			t[i].stu[j].name += nameSeed[j];
    			t[i].stu[j].score = rand() % 61 + 40;
    		}
    	}
    }
    
    void to_print(struct teacher t[],int len) {
    	for (int i = 0; i < len; i++) {
    		cout << "老师的名称为 " << t[i].name << endl;
    		for (int j = 0; j < 5; j++) {
    			cout << "	学生的名称为 " << t[i].stu[j].name << " 成绩为 " << t[i].stu[j].score << endl;
    
    		}
    	}
    }
    
    
    int main() {
    
    	srand((unsigned)(time(NULL)));
    	struct teacher t[3];
    	int len = sizeof(t) / sizeof(teacher);
    	//cout << len << endl;
    
    	to_catch(t, len);
    	to_print(t, len);
    
    	system("pause");
    	return 0;
    }
    

    案例2描述:
    设计一个英雄的结构体,包括成员姓名,年龄,性别;创建结构体数组,数组中存放5名英雄。

    通过冒泡排序的算法,将数组中的英雄按照年龄进行升序排序,最终打印排序后的结果。

    五名英雄信息如下:

    		{"刘备",23,"男"},
    		{"关羽",22,"男"},
    		{"张飞",20,"男"},
    		{"赵云",21,"男"},
    		{"貂蝉",19,"女"},
    
    #include<iostream>
    #include<string>
    #include<ctime>
    using namespace std;
    
    
    struct hero {
    	string name;
    	int age;
    	string sex;
    };
    
    void to_bubble(struct hero h[], int len) {
    	struct hero temp;
    	for (int i = 0; i <len-1 ; i++) {
    		for (int j = i + 1; j < len; j++) {
    			if (h[i].age < h[j].age) {
    				temp = h[i];
    				h[i] = h[j];
    				h[j] = temp;
    			}
    		}
    		
    	}
    
    }
    
    void to_print(struct hero h[], int len) {
    	for (int i = 0; i < len; i++) {
    		cout << h[i].name << "," << h[i].age << endl;
    	}
    }
    
    int main() {
    	struct hero h[5] = {
    		{"刘备",23,"男"},
    		{"关羽",22,"男"},
    		{"张飞",20,"男"},
    		{"赵云",21,"男"},
    		{"貂蝉",19,"女"},
    	};
    
    	struct hero temp;
    	int len = sizeof(h) / sizeof(hero);
    	to_bubble(h, len);
    	to_print(h, len);
    	system("pause");
    	return 0;
    }
