写一个c++程序 基本账户类型包括:普通活期账户、定期存款账户、理财账户、信用卡账户等,通过查找资料了解各种账户的基本属性,通过程序对外接口,能够对各种账户的基本属性进行配置; 2、 具有基本的账户操作功

能，如存款、取款、查询余额、查询交易记录等；3、支持多用户管理，每个用户可以拥有多个账户；4、能够进行简单的账户之间的转账操作。

以下是一个基本的实现示例：

#include <iostream>
#include <vector>
#include <string>

using namespace std;

// 定义账户类
class Account {
public:
    Account(string accountType, double balance): accountType(accountType), balance(balance) {
        // 初始化账户类型和余额
    }

    double getBalance() {
        return balance;
    }

    virtual void deposit(double amount) {
        balance += amount;
    }

    virtual void withdraw(double amount) {
        balance -= amount;
    }

    virtual void display() {
        cout << "Account Type: " << accountType << endl;
        cout << "Balance: " << balance << endl;
    }

protected:
    string accountType; // 账户类型
    double balance; // 余额
};

// 普通活期账户类
class SavingsAccount : public Account {
public:
    SavingsAccount(double balance): Account("Savings Account", balance) {
        // 初始化账户类型和余额
    }
};

// 定期存款账户类
class FixedDepositAccount : public Account {
public:
    FixedDepositAccount(double balance, int term): Account("Fixed Deposit Account", balance), term(term) {
        // 初始化账户类型、余额和期限
    }

    virtual void display() {
        cout << "Account Type: " << accountType << endl;
        cout << "Balance: " << balance << endl;
        cout << "Term: " << term << " months" << endl;
    }

private:
    int term; // 存款期限（月数）
};

// 理财账户类
class InvestmentAccount : public Account {
public:
    InvestmentAccount(double balance, double rate): Account("Investment Account", balance), rate(rate) {
        // 初始化账户类型、余额和利率
    }

    virtual void display() {
        cout << "Account Type: " << accountType << endl;
        cout << "Balance: " << balance << endl;
        cout << "Interest Rate: " << rate << "%" << endl;
    }

private:
    double rate; // 年利率
};

// 信用卡账户类
class CreditCardAccount : public Account {
public:
    CreditCardAccount(double balance, double limit): Account("Credit Card Account", balance), limit(limit) {
        // 初始化账户类型、余额和信用额度
    }

    virtual void display() {
        cout << "Account Type: " << accountType << endl;
        cout << "Balance: " << balance << endl;
        cout << "Credit Limit: " << limit << endl;
    }

private:
    double limit; // 信用额度
};

// 用户类
class User {
public:
    User(string name): name(name) {
        // 初始化用户名
    }

    void addAccount(Account* account) {
        accounts.push_back(account);
    }

    void deposit(int accountIndex, double amount) {
        accounts[accountIndex]->deposit(amount);
    }

    void withdraw(int accountIndex, double amount) {
        accounts[accountIndex]->withdraw(amount);
    }

    void displayAccounts() {
        cout << "User: " << name << endl;

        for (int i = 0; i < accounts.size(); i++) {
            cout << "Account " << i + 1 << ":" << endl;
            accounts[i]->display();
            cout << endl;
        }
    }

    void transfer(int fromAccountIndex, User& toUser, int toAccountIndex, double amount) {
        accounts[fromAccountIndex]->withdraw(amount);
        toUser.deposit(toAccountIndex, amount);
    }

private:
    string name; // 用户名
    vector<Account*> accounts; // 账户列表
};

int main() {
    // 创建用户1
    User user1("Alice");

    // 创建普通活期账户
    SavingsAccount* savingsAccount = new SavingsAccount(1000);
    user1.addAccount(savingsAccount);

    // 创建定期存款账户
    FixedDepositAccount* fixedDepositAccount = new FixedDepositAccount(5000, 12);
    user1.addAccount(fixedDepositAccount);

    // 创建理财账户
    InvestmentAccount* investmentAccount = new InvestmentAccount(20000, 3.5);
    user1.addAccount(investmentAccount);

    // 创建信用卡账户
    CreditCardAccount* creditCardAccount = new CreditCardAccount(0, 5000);
    user1.addAccount(creditCardAccount);

    // 存款
    user1.deposit(0, 500);
    user1.deposit(1, 1000);
    user1.deposit(2, 500);

    // 取款
    user1.withdraw(0, 100);
    user1.withdraw(3, 200);

    // 查询余额和交易记录
    user1.displayAccounts();

    // 创建用户2
    User user2("Bob");

    // 创建普通活期账户
    SavingsAccount* savingsAccount2 = new SavingsAccount(2000);
    user2.addAccount(savingsAccount2);

    // 转账
    user1.transfer(2, user2, 0, 1000);

    // 查询余额和交易记录
    user1.displayAccounts();
    user2.displayAccounts();

    return 0;
}

该程序实现了基本的账户管理功能，可以通过创建不同类型的账户来满足不同的需求，并且支持多用户管理和账户之间的转账操作。
