车辆管理系统设计C++代码

本人用C++写的一个车辆管理系统，主要负责各种车辆的常规信息管理工作。具体代码如下：

#include<iostream.h>

#include<windows.h>

#include<fstream.h>

#define N 20 //车辆总存储量

struct Cars{
int num;
//车辆编号
int pnum;
//车牌号
char made[20];//车辆制造公司
double year;
//车辆购买时间
char type;
//车辆型号，B-大客车，C-小轿车，L-卡车
int km;
//总公里数
int cost;
//基本维护费用

};

class Manager{

private:
Cars car
;
int people
;//载客量
int coach
;
//箱数
int weight
;//载重量
int top;
//记录当前车辆数量

public:
Manager(){top = 0;};//车辆初始值为0
void add();
//添加函数
void search();//查询函数
void show();
//显示函数
void edit();
//编辑函数
void delet();
//删除函数
void sum();
//统计函数
void read();
//读取函数
void write();
//存储函数
void jiemian();//总界面

};

void Manager::add(){
