{

node->display_Node();
Record * r = new Record();
r->set_number(10001);
r->set_passWord("123");

node->set_record(r);
node->display_Node();
return 0;
}
//TestLinklist.cpp:
#include "Linklist.h"

list->display_Linklist();
cout << endl;
Node * n3 = list->find_node(10001); // 先判断是否查找到
if(n3 == NULL)
{
cout << "Not Found..." << endl;
}
else
{
n3->display_Node();
}
return 0;
}
//TestBank.cpp:
#include "Bank.h"
#include <iostream>
using namespace std;
void welcome();
void mainmenu(Bank * bank);
int main()
{

cout << "开户操作：" << endl;

cout << "转账操作：" << endl;

cout << "销户操作：" << endl;
bank->close_account();
return 0;
}
心得体会：
感觉似乎在完成开户功能时，余下的任何代码都是水到渠成的，也在体会类封装与原来的面向过程时所体现的不同。明显的感觉类更加明确清晰，自己在做什么一目了然。而且即使是我做的主函数套用在同学的代码中依然没有任何错误，这很赏心悦目。
