一、头文件创建数据结构
student.h
#pragma once
#include<vector>struct student //定义student结构体 说明学生的基本信息
{ int id;char name[8];int age;int score;
};class View { //定义窗口类 涵盖基本功能和学生数据
private:int id = 1001; //初始学生idvector<student> students; //定义含有student结构体的向量studentsvoid add(); //定义add方法void show();void remove();
public:void list(); //定义控制端展示
};二、构建方法
student.cpp
#include<iostream>
#include<locale>using namespace std;
#include"student.h"void View::list(){while (true){int num;cout << "学生信息管理系统!" << endl;cout << "1.添加信息" << endl;cout << "2.查看信息" << endl;cout << "3.删除信息" << endl;cout << "0.退出" << endl;cout << "请输入:"; cin >> num;if (num == 0) break;else if (num == 1) this->add();else if (num == 2) this->show();else if (num == 3) this->remove();else {cout << "输入有误，请重新输入！";continue;};}
}void View::add() {while (true){student stu;char name[9]; int age, score;cout << "请输入姓名，年龄，分数:"; cin >> name >> age >> score;stu.age = age; stu.score = score; stu.id = this->id;strcpy_s(stu.name, sizeof(stu.name), name);this->students.push_back(stu); // 使用 push_back 向 students vector 中添加元素student结构体this->id++;cout << "添加成功！" << endl;break;}}
void View::show() {int length = this->students.size();for (int i = 0; i < length; i++){cout << this->students[i].id << "\t";cout << this->students[i].name << "\t";cout << this->students[i].age << "\t";cout << this->students[i].score << endl;}
}void View::remove() {int num;int flag;cout << "请输入需要删除的编号:"; cin >> num;int length = this->students.size();for (int i = 0; i < length; i++){if (this->students[i].id == num){this->students.erase(this->students.begin() + i);flag = 0;break;}else { flag = 1; };};if (flag == 1) {cout << "没有该学生" << endl;}else{cout << "删除成功!" << endl;}
}三、主函数初始化窗口
main.cpp
#include<locale>
#include <iostream>
using namespace std;
#include "student.h"int main()
{View view;view.list();
}
