c语言编写银行业务模拟程序,c语言银行业务模拟

好的，下面给您提供一个简单的银行业务模拟程序的C语言代码示例。

#include <stdio.h>
#include <stdlib.h>
#include <time.h>

#define MAX_CUSTOMERS 5 // 最大顾客数
#define MINUTES_PER_HOUR 60 // 每小时分钟数

// 枚举所有可能的银行业务类型
enum TransactionType { DEPOSIT, WITHDRAWAL, CHECK_BALANCE };

// 银行账户结构体
typedef struct {
    int accountNumber;
    float balance;
} Account;

// 银行业务结构体
typedef struct {
    int customerNumber;
    enum TransactionType type;
    float amount;
} Transaction;

// 顾客结构体
typedef struct {
    int customerNumber;
    Account account;
    Transaction transactions[10]; // 最多存储10个银行业务
} Customer;

// 银行结构体
typedef struct {
    Customer customers[MAX_CUSTOMERS]; // 最多存储5个顾客
    int customerCount;
} Bank;

// 初始化银行账户
void initializeAccounts(Bank *bank) {
    for (int i = 0; i < bank->customerCount; i++) {
        bank->customers[i].account.accountNumber = 1000 + i;
        bank->customers[i].account.balance = rand() % 100000; // 随机生成一个0~99999之间的随机数
    }
}

// 在银行中查找一个账户
Account *findAccount(Bank *bank, int accountNumber) {
    for (int i = 0; i < bank->customerCount; i++) {
        if (bank->customers[i].account.accountNumber == accountNumber) {
            return &bank->customers[i].account;
        }
    }
    return NULL;
}

// 执行一个存款业务
void doDeposit(Bank *bank, int customerNumber, float amount) {
    Account *account = &bank->customers[customerNumber].account;
    account->balance += amount;
    Transaction transaction = { customerNumber, DEPOSIT, amount };
    bank->customers[customerNumber].transactions[0] = transaction;
}

// 执行一个取款业务
void doWithdrawal(Bank *bank, int customerNumber, float amount) {
    Account *account = &bank->customers[customerNumber].account;
    if (account->balance >= amount) {
        account->balance -= amount;
        Transaction transaction = { customerNumber, WITHDRAWAL, amount };
        bank->customers[customerNumber].transactions[0] = transaction;
    }
}

// 执行一个余额查询业务
void doCheckBalance(Bank *bank, int customerNumber) {
    Account *account = &bank->customers[customerNumber].account;
    Transaction transaction = { customerNumber, CHECK_BALANCE, account->balance };
    bank->customers[customerNumber].transactions[0] = transaction;
}

// 随机执行一个顾客的银行业务
void doRandomTransaction(Bank *bank) {
    int customerIndex = rand() % bank->customerCount;
    int transactionType = rand() % 3;
    float amount = rand() % 10000;
    switch (transactionType) {
        case 0:
            doDeposit(bank, customerIndex, amount);
            printf("Customer %d deposited $%.2f.\n", customerIndex, amount);
            break;
        case 1:
            doWithdrawal(bank, customerIndex, amount);
            printf("Customer %d withdrew $%.2f.\n", customerIndex, amount);
            break;
        case 2:
            doCheckBalance(bank, customerIndex);
            printf("Customer %d checked their balance.\n", customerIndex);
            break;
    }
}

// 显示一个顾客的银行业务历史记录
void displayTransactions(Bank *bank, int customerNumber) {
    printf("Transaction history for customer %d:\n", customerNumber);
    for (int i = 0; i < 10 && bank->customers[customerNumber].transactions[i].type != 0; i++) {
        Transaction transaction = bank->customers[customerNumber].transactions[i];
        switch (transaction.type) {
            case DEPOSIT:
                printf("Deposit of $%.2f\n", transaction.amount);
                break;
            case WITHDRAWAL:
                printf("Withdrawal of $%.2f\n", transaction.amount);
                break;
            case CHECK_BALANCE:
                printf("Balance check - current balance is $%.2f\n", transaction.amount);
                break;
        }
    }
}

int main() {
    srand(time(NULL)); // 初始化随机数生成器
    Bank bank = { 0 };
    bank.customerCount = 3;
    initializeAccounts(&bank);

    for (int i = 0; i < MINUTES_PER_HOUR * 8; i++) { // 模拟一整个工作日，即8小时
        doRandomTransaction(&bank);
    }

    displayTransactions(&bank, 0);

    return 0;
}

这个程序模拟了一个简单的银行业务系统，包括顾客账户、银行业务类型、银行账户、顾客结构体和银行结构体等。程序随机执行银行业务，并且允许您查看一个顾客的银行业务历史记录。请注意，这只是一个简单的示例，您可以根据自己的需求进行修改和扩展。
