商城小程序源码|开源小程序商城完整源码附视频搭建教程

商城小程序是基于微信、抖音和头条等第三方平台为基础构建的社区电商购物系统。在本文中我们将讨论小程序商场源码的架构思路和基本方法。

商城小程序源码所要提供的功能

1、用户可以下单并购买商品。

2、用户将能够添加购物车。

3、用户便捷的支付系统。

4、用户可以查看订单状态和历史记录。

设计思路：

首先，将向客户显示菜单。选择后，所有产品及其价格将显示出来。然后客户将选择产品并选择数量（产品数量）。这个过程一直持续到购物完成。每当顾客完成他的购物的数量和单价后，最后要支付的总额显示出来。

以下是上述功能的实现：

// C++ program to implement the program
// that illustrates Online shopping
#include <bits/stdc++.h>
#include <cstring>
#include <iostream>
#include <map>
using namespace std;
 
char c1, confirm_quantity;
float quantity;
int selectedNum;
double total_amount = 0;
int flag = 0;
 
// Stores items with their corresponding
// price
map<string, double> items = {
	{ "Samsung", 15000 },
	{ "Redmi", 12000 },
	{ "Apple", 100000 },
	{ "Macbook", 250000 },
	{ "HP", 40000 },
	{ "Lenovo", 35000 },
	{ "C", 1000 },
	{ "C++", 3000 },
	{ "Java", 4000 },
	{ "Python", 3500 }
};
 
// Stores the selected items with
// their quantity
map<string, int> selected_items;
 
// Function to print the bill after shopping
// is completed prints the items, quantity,
// their cost along with total amount
void printBill(map<string, double> items,
			map<string, int> selected_items,
			float total_amount)
{
	cout << "Item	 "
		<< "Quantity	 "
		<< "Cost\n";
 
	for (auto j = selected_items.begin();
		j != selected_items.end(); j++) {
		cout << j->first << "	 ";
		cout << j->second << "		 ";
		cout << (selected_items[j->first])
					* (items[j->first])
			<< endl;
	}
 
	cout << "-----------------------"
		<< "-------------\n";
	cout << "Total amount:			 "
		<< total_amount << endl;
	cout << "-----------------------"
		<< "-------------\n";
	cout << "*****THANK YOU && HAPPY"
		<< " ONLINE SHOPPING*****";
}
 
// Function to ask the basic details of
// any customer
void customerDetails()
{
 
	cout << "Enter your name: ";
	string customer_name;
	getline(cin, customer_name);
 
	cout << "WELCOME ";
	for (int i = 0;
		i < customer_name.length();
		i++) {
		cout << char(toupper(
			customer_name[i]));
	}
	cout << "\n";
}
 
// showMenu() is to print the
// menu to the user
void showMenu()
{
	cout << "Menu\n";
	cout << "= = = = = = = = "
		<< " = = = = = \n";
	cout << "1.Mobile\n2.laptop\n3"
		<< ".Computer courses\n";
	cout << "=
