定义一个类来表示银行账户

#include<iostream>
using namespace std;
class BankAccount

    string m_name;
    string m_num;
    unsigned int m_balance;
    public:

                m_balance = balance;
            }
            void show() const
            {

                cout << m_num << endl;
                cout << m_balance << endl;

                else
