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：
