使用C++的ATM管理系统

自动取款机是用来携带一天到一天的金融交易自动柜员机。自动柜员机可用于取款，存款或什至了解帐户信息(如余额等)。它们既方便又易于使用，它使消费者可以进行快速的自助交易。

在本文中，我们将讨论C++中的ATM管理系统，它是一个为用户提供实际自动柜员机(即ATM)应具备的各个方面的应用程序。它是具有ATM功能的菜单驱动程序，其中包括：

1. Enter Name, Account number, Account type to be shown during transactions.
2. Shows the information about the person who is doing the transaction.
3. Enter amount to deposited in the account.
4. Shows the Balance in the account.
5. Enter amount to be withdrawn from the account, and then it shows available balance.
6. Cancel the transaction.

方法：该程序使用类的基本概念，C++中的访问修饰符，数据类型，变量，切换用例等。下面是要实现的功能：

• setvalue() ：此函数用于在C++中使用基本的输入和输出方法(即cout和cin语句)设置数据，这些语句显示并分别从键盘(即从用户)获取和获取输入。
• showvalue ()：此函数用于打印数据。
• deposit()：此函数有助于将钱存入特定帐户。
• showbal( )：此函数显示沉积后可用的总平衡。
• withdrawl()： 此函数有助于从帐户中提取资金。
• main() ：此函数在无限的while循环内有一个简单的切换条件(做出选择) ，以便每次用户选择选择时。

以下是使用上述方法的C++程序：

C++

// C++ program to implement the ATM
// Management System
#include 
#include 
#include 
using namespace std;
class Bank {
  
    // Private variables used inside class
private:
    string name;
    int accnumber;
    char type[10];
    int amount = 0;
    int tot = 0;
  
    // Public variables
public:
    // Function to set the person's data
    void setvalue()
    {
        cout << "Enter name\n";
        cin.ignore();
  
        // To use space in string
        getline(cin, name);
  
        cout << "Enter Account number\n";
        cin >> accnumber;
        cout << "Enter Account type\n";
        cin >> type;
        cout << "Enter Balance\n";
        cin >> tot;
    }
  
    // Function to display the required data
    void showdata()
    {
        cout << "Name:" << name << endl;
        cout << "Account No:" << accnumber << endl;
        cout << "Account type:" << type << endl;
        cout << "Balance:" << tot << endl;
    }
  
    // Function to deposit the amount in ATM
    void deposit()
    {
        cout << "\nEnter amount to be Deposited\n";
        cin >> amount;
    }
  
    // Function to show the balance amount
    void showbal()
    {
        tot = tot + amount;
        cout << "\nTotal balance is: " << tot;
    }
  
    // Function to withdraw the amount in ATM
    void withdrawl()
    {
        int a, avai_balance;
        cout << "Enter amount to withdraw\n";
        cin >> a;
        avai_balance = tot - a;
        cout << "Available Balance is" << avai_balance;
    }
};
  
// Driver Code
int main()
{
    // Object of class
    Bank b;
  
    int choice;
  
    // Infinte while loop to choose
    // options everytime
    while (1) {
        cout << "\n~~~~~~~~~~~~~~~~~~~~~~~~~~"
             << "~~~~~~~~~~~~~~~~~~~~~~~~~~~~"
             << "~~~WELCOME~~~~~~~~~~~~~~~~~~"
             << "~~~~~~~~~~~~~~~~~~~~~~~~~~~~"
             << "~~~~~~~~~\n\n";
        cout << "Enter Your Choice\n";
        cout << "\t1. Enter name, Account "
             << "number, Account type\n";
        cout << "\t2. Balance Enquiry\n";
        cout << "\t3. Deposit Money\n";
        cout << "\t4. Show Total balance\n";
        cout << "\t5. Withdraw Money\n";
        cout << "\t6. Cancel\n";
        cin >> choice;
  
        // Choices to select from
        switch (choice) {
        case 1:
            b.setvalue();
            break;
        case 2:
            b.showdata();
            break;
        case 3:
            b.deposit();
            break;
        case 4:
            b.showbal();
            break;
        case 5:
            b.withdrawl();
            break;
        case 6:
            exit(1);
            break;
        default:
            cout << "\nInvalid choice\n";
        }
    }
}

输出：

• 显示选择：
  
• 对于选择1：
  
• 对于选择3：
  
• 对于选择2：
  
• 对于选择5：
