C++ 管理系统案例代码完整实现源码分享

无论你是初学者还是已经有了一定编程基础的开发者，学习和实现C++管理系统都是非常有用的。C++管理系统是一种非常重要的应用程序，可以帮助管理者对自己的业务和项目进行更好地组织和规划，以提高效率和管理水平。在本文中，我们将分享一个 C++管理系统案例代码的完整实现和源码，帮助大家更好地理解如何实现一个C++管理系统。

一、项目介绍

这个C++管理系统是一个基于控制台的简单项目，旨在帮助用户管理商店中的库存和销售记录。这个C++管理系统的功能非常实用，方便管理者进行商店的管理。整个系统分为两个部分：商品管理和销售管理。在商品管理模块中，用户可以添加、修改、删除和查询商品信息，而在销售管理模块中，用户可以查看销售记录和计算销售数据。

二、系统实现

以下是C++管理系统案例代码的主要实现：

1、定义Product类，用于管理商品信息


class Product {
 int product_id;
 string product_name;
 float product_price;
 int product_quantity;
public:
 Product();
 Product(int id, string name, float price, int quantity);
 bool operator==(const Product& product) const;
 void display();
 int get_id();
 string get_name();
 float get_price();
 int get_quantity();
};

2、定义ProductManager类，用于管理商品信息


class ProductManager {
 vector<Product> products;
public:
 void add_product(Product product);
 void delete_product(int id);
 void update_product(int id, Product product);
 Product find_product(int id);
 void display_all();
};

3、定义Sale类，用于管理销售信息


class Sale {
 int sale_id;
 int product_id;
 float sale_price;
 int sale_quantity;
 float sale_total_price;
 time_t sale_time;
public:
 Sale();
 Sale(int id, int product_id, float price, int quantity, float total_price, time_t time);
 bool operator==(const Sale& sale) const;
 void display();
 int get_id();
 int get_product_id();
 float get_price();
 int get_quantity();
 float get_total_price();
 time_t get_time();
};

4、定义SalesManager类，用于管理销售信息


class SalesManager {
 vector<Sale> sales;
public:
 void add_sale(Sale sale);
 void delete_sale(int id);
 void display_all();
 float calculate_sales_revenue();
};

5、定义MainMenu类，实现控制台用户界面


class MainMenu {
 ProductManager product_manager;
 SalesManager sales_manager;
public:
 void run();
 void display_menu();
};

三、源码分享
