基于MVC（Model-View-Controller）架构的小型应用程序。模拟一个简单的银行账户管理系统，包括账户模型、用户界面和控制器。
Model（模型）
// Account.h
#ifndef ACCOUNT_H
#define ACCOUNT_H#include <string>class Account {
private:std::string accountNumber;double balance;public:Account(const std::string& number, double initialBalance) : accountNumber(number), balance(initialBalance) {}void deposit(double amount) {if (amount > 0) {balance += amount;}}bool withdraw(double amount) {if (amount > 0 && balance >= amount) {balance -= amount;return true;}return false;}double getBalance() const {return balance;}const std::string& getAccountNumber() const {return accountNumber;}
};#endif // ACCOUNT_H
View（视图）
// AccountView.h
#ifndef ACCOUNTVIEW_H
#define ACCOUNTVIEW_H#include "Account.h"
#include <iostream>class AccountView {
public:void displayAccountInfo(const Account& account) {std::cout << "Account Number: " << account.getAccountNumber() << std::endl;std::cout << "Balance: $" << account.getBalance() << std::endl;}void displayTransactionResult(bool success) {if (success) {std::cout << "Transaction successful." << std::endl;} else {std::cout << "Transaction failed." << std::endl;}}
};#endif // ACCOUNTVIEW_H
Controller（控制器）
// AccountController.h
#ifndef ACCOUNTCONTROLLER_H
#define ACCOUNTCONTROLLER_H#include "Account.h"
#include "AccountView.h"class AccountController {
private:Account account;AccountView view;public:AccountController(const std::string& number, double initialBalance) : account(number, initialBalance), view() {}void deposit(double amount) {account.deposit(amount);view.displayTransactionResult(true);}void withdraw(double amount) {bool success = account.withdraw(amount);view.displayTransactionResult(success);}void displayAccountInfo() {view.displayAccountInfo(account);}
};#endif // ACCOUNTCONTROLLER_H
Main（主函数）
// main.cpp
#include "AccountController.h"
#include <iostream>int main() {// 创建一个账户AccountController myAccount("123456789", 1000.0);// 显示账户信息myAccount.displayAccountInfo();// 执行存款操作std::cout << "Depositing $500..." << std::endl;myAccount.deposit(500.0);// 执行取款操作std::cout << "Withdrawing $200..." << std::endl;myAccount.withdraw(200.0);// 再次显示账户信息std::cout << "Account info after transactions:" << std::endl;myAccount.displayAccountInfo();return 0;
