小白的C++之路——结构体

结构体与数组不同的是结构体能包含不同类型的数据，像一个综合性的仓库，更加灵活。

#include <iostream>

#include <string>

#include <iomanip>

using namespace std;

struct Student

{

    int number;

    string name;

    int grade1;

    int grade2;

    int grade3;

    float score;

}stu[];

int main() {

    int num;

    int i, j;

    cout << "请输入学生人数：" << endl;

    cin >> num;

    for (i = ; i < num; i++) {

        stu[i].score = (stu[i].grade1 + stu[i].grade2 + stu[i].grade3) / ;

        cout << "学号：";     cin >> stu[i].number;

        cout << "姓名：";     cin >> stu[i].name;

        cout << "语文成绩："; cin >> stu[i].grade1;

        cout << "数学成绩："; cin >> stu[i].grade2;

        cout << "英语成绩："; cin >> stu[i].grade3;

        stu[i].score = (stu[i].grade1 + stu[i].grade2 + stu[i].grade3) / ;

    }

    cout << setw() << "学号：" << setw() << "姓名：" << setw() << "语文成绩：";

    cout << setw() << "数学成绩：" << setw() << "英语成绩：" << setw() << "平均成绩：" << endl;

    for (i = ; i < num; i++) {

        cout << setw() << stu[i].number << setw() << stu[i].name << setw() << stu[i].grade1;

        cout << setw() << stu[i].grade2 << setw() << stu[i].grade3 << setw() << stu[i].score << endl;

    }

    return ;

}

简单的小程序，会在今后的学习中逐渐完善与丰富这个程序

运行结果如下：
