c语言编写银行业务模拟程序

C语言编写银行业务模拟程序可以涉及账户管理、交易操作、存款、取款、转账等功能。以下是一个简单的例子，展示如何创建一个银行账户类和处理一些基本操作：

#include <stdio.h>

// 定义银行账户结构体
typedef struct {
    char account_number[10];
    char customer_name[50];
    float balance;
} BankAccount;

// 初始化账户
BankAccount* create_account(char name[], float initial_deposit) {
    BankAccount *account = (BankAccount*)malloc(sizeof(BankAccount));
    strcpy(account->account_number, "XXXXXX");
    strcpy(account->customer_name, name);
    account->balance = initial_deposit;
    return account;
}

// 存款函数
void deposit(BankAccount* account, float amount) {
    if(amount > 0) {
        account->balance += amount;
        printf("存入了%.2f元，当前余额为%.2f\n", amount, account->balance);
    } else {
        printf("无法存款，金额必须为正。\n");
    }
}

// 取款函数
void withdraw(BankAccount* account, float amount) {
    if(amount <= account->balance) {
        account->balance -= amount;
        printf("取出了%.2f元，当前余额为%.2f\n", amount, account->balance);
    } else {
        printf("取款失败，余额不足。\n");
    }
}

// 转账函数
void transfer(BankAccount* from_account, BankAccount* to_account, float amount) {
    if(amount <= from_account->balance) {
        withdraw(from_account, amount);
        deposit(to_account, amount);
        printf("转账%.2f元成功，从%.2f元变为%.2f元，转出到%.2f元变%.2f元\n",
            amount, from_account->balance, from_account->balance,
            to_account->balance, to_account->balance);
    } else {
        printf("转账失败，余额不足。\n");
    }
}

int main() {
    BankAccount* account1 = create_account("张三", 1000.00);
    BankAccount* account2 = create_account("李四", 500.00);

    // 模拟业务操作
    deposit(account1, 500);
    withdraw(account2, 200);
    transfer(account1, account2, 300);

    return 0;
}
