C语言ATM代码

以下是一个简单的C语言ATM机代码示例，包括账户余额、取款和存款功能。

#include <stdio.h>

int main()
{
    int balance = 1000, choice, amount;

    printf("Welcome to the ATM machine!\n");
    printf("Your current balance is %d\n\n", balance);

    while(1) {
        printf("Please select an option:\n");
        printf("1. Withdraw money\n");
        printf("2. Deposit money\n");
        printf("3. Exit\n\n");

        scanf("%d", &choice);

        switch(choice) {
            case 1:
                printf("Enter the amount to withdraw: ");
                scanf("%d", &amount);
                if(amount > balance) {
                    printf("Insufficient balance! Please try again.\n\n");
                } else {
                    balance -= amount;
                    printf("Withdrawal successful. Your new balance is %d\n\n", balance);
                }
                break;
            case 2:
                printf("Enter the amount to deposit: ");
                scanf("%d", &amount);
                balance += amount;
                printf("Deposit successful. Your new balance is %d\n\n", balance);
                break;
            case 3:
                printf("Thank you for using our ATM. Goodbye!\n");
                return 0;
            default:
                printf("Invalid option! Please try again.\n\n");
                break;
        }
    }
}

这是一个非常基本的ATM机程序，可以根据需求进行修改和扩展。请注意，这只是一个演示用代码，实际上ATM机的安全性非常重要，需要进行更严格的安全措施和防范措施。
