Question

我在交易类中需要帮助：

包含以下数据的事务类：

用于跟踪交易数量的计数器。每笔存款增加或退出了。客户只需一次登录即可完成5笔交易。 o 5种可能的交易历史。这将是一个美元金额的数组，其中a 负数是提款，正数是存款。清除历史每次客户登录时。

交易对象将执行以下操作： o更新历史记录以反映用户登录时所做的任何事务。跟踪每个交易价值如上所述在交易数据部分中进行。后每个事务，增加事务计数器。 o清除所有存储金额的历史记录并重置交易计数

帐户类的一些代码

public double getBalance()
{
return customerBalance;
 }
public void  Customerdeposit()
 {
double deposit = Convert.ToDouble(Console.ReadLine());
if (deposit <= 0)
 {
Console.WriteLine("\nCannot Deposit");
}
else
 {
customerBalance = customerBalance + deposit;
}
}
public void customerWithdraw()
{
double withdraw = Convert.ToDouble(Console.ReadLine());
{
if (withdraw >= 0)
{
customerBalance = customerBalance - withdraw;
}
else
{
Console.WriteLine("There is not Sufficient fund in your account to withdraw");
} }}}

我尝试使用下面的代码为事务类编写代码但obj.Customerdeposit（金额）有很多错误;如果条件和更新（金额）;

     class Transaction
       {
        private int[] arr;
        private int cntr;

        Transaction()
        {
            arr = new int[5];
            cntr = 0;
        }
        private void update(int amount)
        {
            arr[cntr] = amount;
            cntr++;
     }
    public void credit(Account obj, int amount)
    {
    if(cntr!=5)
    {
        obj.Customerdeposit(amount);
        return;
        Update(amount);

     }
    else
    {
    Console.WriteLine("Transaction limit exceeded");        
    }}
     public void debit(Account obj, int amount)
    {
    if(cntr!=5)
    {
    obj.customerWithdraw(amount);
    return;
    Update(-amount);
    }
    else
    {
    Console.WriteLine("Transaction limit exceeded");        
}    
}
}
}

您已经指定了从属性到函数的所有内容，只需编写代码即可。

现在这将是勺子喂食，但是，你的改变也是错误的。

帐户类：

public double getBalance()
{
return customerBalance;
 }
public bool Customerdeposit()
 {
double deposit = Convert.ToDouble(Console.ReadLine());
if (deposit <= 0)
 {
return false;
}
customerBalance = customerBalance + deposit;
return true;
}

public bool customerWithdraw()
{
double withdraw = Convert.ToDouble(Console.ReadLine());
{
if (withdraw <= 0 || customerBalance < withdraw )
{
return false;
}
customerBalance = customerBalance - withdraw;
return true;
}
}
 }

现在您的TransactionClass可以是：（自己添加其他功能）

class Transaction
{
private int[] arr;
private int cntr;
    Transaction()
{
    arr = new int[5];
    cntr = 0;
}

    private void update(int amount)
{
    arr[cntr]=amount;
    cntr++;
}

    public void credit(Account obj, int amount)
{
    if(cntr!=5)
    {
        if(obj.CustomerDeposit(amount))
        Update(amount);   //works only when true returned from above.
        else
        //print message 


    }
    else
    Console.WriteLine("Transaction limit exceeded");        
}

    public void debit(Account obj, int amount)
{
    if(cntr!=5)
    {
        if(obj.CustomerWithdraw(amount))
        Update(-amount);
        else
        //print any message 

    }
    else
    Console.WriteLine("Transaction limit exceeded");        
}

}

将对每笔交易进行调用：

Transaction trans= new Transaction();
trans.credit(myCustAcc[user],500);
