2117 - 面向对象之存折类
请定义“存折”类，及其相关的客户端代码。请注意编写正确的构造函数。存折类的基本情况如下：
Type name：AccountType
Domain:
Id，name，balance;
Operations:
Deposit, 存钱操作；
Withdraw，取钱操作；
getBalance，获取余额操作；
WriteAccount，打印帐户信息；
Input：
13001 peter 0
1200 //存的钱
500 //取的钱
Output：
13001 peter 700
Input
13001 peter 0//Id，name,balance
1200 //存的钱
500 //取的钱
Output
13001 peter 700//id name 剩余的金额
Examples
Input
13001 peter 0 1200 500
Output
13001 peter 700
Solution C++
#include <iostream> #include <string> using namespace std; class AccountType { public: void set(); void cunqian(); void quqian(); void chayue(); void dayinxinxi(); private: int id; string name; double balance; }; void AccountType::set() { cin>>id; cin>>name; cin>>balance; } void AccountType::cunqian() { int temp; cin>>temp; balance=balance+temp; } void AccountType::quqian() { int temp; cin>>temp; balance=balance-temp; } void AccountType::chayue() { cout<<balance<<endl; } void AccountType::dayinxinxi() { cout<<id<<" "<<name<<" "<<balance<<endl; } int main() { AccountType mouren; mouren.set(); mouren.cunqian(); mouren.quqian(); mouren.dayinxinxi(); return 0; }
