atm取款机c语言代码

以下是一个简单的 ATM 取款机 C 语言代码：

#include <stdio.h>

int main()
{
    int balance = 10000, withdraw, deposit;
    int option, pin = 1234;

    printf("Welcome to the ATM!\n");
    printf("Enter your PIN: ");
    scanf("%d", &pin);

    if (pin != 1234) {
        printf("Invalid PIN. Try again.\n");
        return 0;
    }

    printf("Select an option:\n");
    printf("1. Check balance\n");
    printf("2. Withdraw money\n");
    printf("3. Deposit money\n");
    scanf("%d", &option);

    switch (option) {
    case 1:
        printf("Your balance is %d\n", balance);
        break;
    case 2:
        printf("Enter the amount to withdraw: ");
        scanf("%d", &withdraw);
        if (withdraw > balance) {
            printf("Insufficient balance.\n");
        } else {
            balance -= withdraw;
            printf("Your new balance is %d\n", balance);
        }
        break;
    case 3:
        printf("Enter the amount to deposit: ");
        scanf("%d", &deposit);
        balance += deposit;
        printf("Your new balance is %d\n", balance);
        break;
    default:
        printf("Invalid option selected.\n");
    }

    printf("Thank you for using the ATM!\n");

    return 0;
}

这个代码实现了一个简单的 ATM 取款机，包括 PIN 验证、查询余额、取款和存款等功能。当然，这只是一个简单的示例，实际的 ATM 取款机肯定要更复杂和安全。
