Question

一个新手关于C++编程的问题

我是大一的新生 才开始学c++ 遇到一道题 要编一个简单的银行存款 取款 查询余额的程序 我自己写了个 但是总是有错误 谁能帮我修改一下 。。
由于是大一的新生 尽量保持原创 就用我写的里面自带的语言
麻烦修改过后贴上来
实在是麻烦了 谢谢好心人。！

#include <iostream>
using std::cout;
using std::endl;

#include <string>
using std::string;

class Account
{
public:
Account(string initialBalance)
{ if(initialBalance>=0)
accountBalance=initialBalance;
if(initialBalance<0)
{ accountBalance=0;
cout<<"the initial balance was invalid"<<endl;
}
}
void Credit(string deposit)
{
presentAccountBalance=accountBalance+deposit;
}
void debit(string money)
{
if(money<=accountBalance)
presentAccountBalance=accountBalance-money;
if(money>accountBalance)
{
presentAccountBalance=accountBalance;
cout<<"Debit amount exceeded account balance"<<endl;
}
}
void getBalance()
{
cout<<"the present account balance is:"<<presentAccountBalance<<"!"<<endl;
}
}
int main()
{
int accountBalance;
string presentAccountBalance;
string initialBalance;
string deposit;
string money;

Account account1;
Account account2;

cout<<"please enter the initial balance for the account1:"<<endl;
getline(cin,initialBalance);
cout<<"please enter the initial balance for the account2:"<<endl;
getline(cin,initialBalance);

cout<<"please enter the deposit for the account1:"<<endl;
getline(cin,deposit);
cout<<"please enter the deposit for the account2:"<<endl;
getline(cin,deposit);

cout<<"please enter the money you want to take out from account1:"<<endl;
getline(cin,money);
cout<<"please enter the money you want to take out from account2:"<<endl;
getline(cin,money);
return 0
}
题目是这样的:创建一个Account的类 银行可以使用它表示客户的银行账户 这个类应该包括一个类型为int的数据成员 表示账户余额 这个类必须提供一个构造函数 它接受初始余额并用它初始化数据成员
这个构造函数应当确认初始余额的有效性 保证他大于或等于0 否则余额设定为0 并且显示错误信息

该类还要提供3个成员函数 存款 取款 和返回当前余额（getBalance) 具体的我写在程序里了 修改下 不要使用新的函数 我们还没学过。。

Answer 1

= =这变量名..好长了...哈哈
是这样子的， int accountBalance;
string presentAccountBalance;
string initialBalance;
string deposit;
string money;这些应该都作为类的成员变量，
而且在你的程序里也没看到你用你写的成员函数了啊

类最后的｝ 后要加;
===========
建议你好好看看书上的例子把，这代码写的不合理

#include <iostream>
using std::cout;
using std::cin;
using std::endl;

#include <string>
using std::string;

class Account
{
double accountBalance;
double presentAccountBalance;
double initialBalance;
double deposit;
double money;
public:
Account()
{ cout<<"please enter the initial balance for the account:"<<endl;
cin>>initialBalance;
if(initialBalance>=0)
accountBalance=initialBalance;
if(initialBalance<0)
{ accountBalance=0;
cout<<"the initial balance was invalid"<<endl;
}
}
void Credit()
{
cout<<"please enter the deposit for the account:"<<endl;
cin>>deposit;
presentAccountBalance=accountBalance+deposit;
}
void debit()
{
cout<<"please enter the money you want to take out from account:"<<endl;
cin>>money;
if(money<=accountBalance)
presentAccountBalance=accountBalance-money;
if(money>accountBalance)
{
presentAccountBalance=accountBalance;
cout<<"Debit amount exceeded account balance"<<endl;
}
}
void getBalance()
{
cout<<"the present account balance is:"<<presentAccountBalance<<"!"<<endl;
}
};
int main()
{

Account account1;
Account account2;
account1.Credit();
account1.debit();
account1.getBalance();
account2.Credit();
account2.debit();
account2.getBalance();

return 0;
}

Answer 2

class后加了一个分号，结果四十几个错误。。。改还不如直接写一个了
