语言要求 c语言 场景说明: 设计一个简单的银行账户类,包含以下基本方法: 开户:用户可以通过构造函数或特定的方法(如openaccount)来开设一个新账户,需要设置账户的初始余额(默认为0)。 存款:提供一个deposit方法,获取该账户,允许用户向账户中存入一定金额。 取款:提供一个withdraw方法,允许用户从账户中取出一定金额,但需要注意账户余额不能小于取款金额,否则应抛出余额不足异常。 查询余额:提供一个getbalance方法,用于返回当前账户的余额。 你需要在c或java代码里做如下几件事: 1、实现上述功能的bankaccount类。 2、并写一个测试类bankaccounttest,写4个测试方法,都放到main里面,一次性分别按如下顺序执行: 方法①开户-存款20-取款19.89-查询余额 方法②开户-存款20-取款21.01-查询余额 方法③存款20-开户-取款19.89-查询余额 方法④取款20-开户-存款20.01-查询余额 用于验证bankaccount类的各个功能是否按预期工作,①②③④方法为连贯执行,每一个方法执行完,恢复初始状态,②开始执行,以


根据你的需求,我们将使用C语言实现一个简单的银行账户管理程序。由于C语言不像Java那样支持类和对象,我们将使用结构体来模拟类的行为,并通过函数来实现类的方法。C语言没有内置的异常处理机制,因此对于余额不足的情况,我们将通过返回值的方式来处理。 首先,我们定义`BankAccount`结构体,并实现相关功能。 1. 实现 `BankAccount` 结构体及功能 ```c #include <stdio.h> typedef struct { double balance; } BankAccount; // 开户 void openAccount(BankAccount *account, double initialBalance) { account->balance = initialBalance; } // 存款 void deposit(BankAccount *account, double amount) { account->balance += amount; } // 取款 int withdraw(BankAccount *account, double amount) { if (account->balance >= amount) { account->balance -= amount; return 1; // 成功 } return 0; // 失败 } // 查询余额 double getBalance(const BankAccount *account) { return account->balance; } ``` 2. 测试类 `BankAccountTest` 接下来,我们将创建一个测试函数 `BankAccountTest` 来验证上述功能。 ```c void BankAccountTest() { BankAccount account; // 方法① 开户-存款20-取款19.89-查询余额 openAccount(&account, 0); deposit(&account, 20); withdraw(&account, 19.89); printf("Method 1 - Balance: %.2f\n", getBalance(&account)); // 方法② 开户-存款20-取款21.01-查询余额 openAccount(&account, 0); deposit(&account, 20); if (!withdraw(&account, 21.01)) { printf("Method 2 - Insufficient funds for withdrawal.\n"); } else { printf("Method 2 - Balance: %.2f\n", getBalance(&account)); } // 方法③ 存款20-开户-取款19.89-查询余额 openAccount(&account, 0); deposit(&account, 20); withdraw(&account, 19.89); printf("Method 3 - Balance: %.2f\n", getBalance(&account)); // 方法④ 取款20-开户-存款20.01-查询余额 openAccount(&account, 0); deposit(&account, 20.01); if (!withdraw(&account, 20)) { printf("Method 4 - Insufficient funds for withdrawal.\n"); } else { printf("Method 4 - Balance: %.2f\n", getBalance(&account)); } } int main() { BankAccountTest(); return 0; } ``` 这段代码实现了你的所有要求。每个测试方法都在一个连贯的过程中执行,并且在每个方法执行之后都会重置账户状态以便于下一个测试。希望这能满足你的需求!
