C++銀行管理系統(tǒng)

2、存在文件中，退出系統(tǒng)后再次運(yùn)行系統(tǒng)，之前注冊(cè)的用戶和存款信息都存在。二 程序?qū)崿F(xiàn)的大致思路：1. 登陸界面和主界面的設(shè)計(jì)采用一行行printf輸出。2. 登陸界面->主界面的切換采用system(“cls)函數(shù)。3. 主界面的所有操作都涉及到了文件操作，所以采用3個(gè)文件分開儲(chǔ)存和讀取的方式。（1） 存取款以及查詢余額：（2） 歷史記錄：（3） 賬戶密碼信息：三、程序算法和數(shù)據(jù)結(jié)構(gòu)：1.登陸用戶：從文件里面讀取信息，把用戶名和密碼分別壓棧，讀取結(jié)束，驗(yàn)證用戶的名字和密碼和棧頂元素是否匹配，不匹配棧頂元素出棧，直到棧的容量是空的時(shí)候。返回信息：用戶或者密碼錯(cuò)誤。2.存款取款以及余額的查詢：每

3、次建立一個(gè)新的用戶的時(shí)候，初始化此用戶的所有信息。主要是針對(duì)的余額。從文件里面讀取信息，采用二叉樹的結(jié)構(gòu)搜索用戶。來實(shí)現(xiàn)查找。采用文件的重新寫入來實(shí)現(xiàn)存取款。四、程序的一些設(shè)計(jì)的技巧以及注意情況：為了使程序模塊化，我們要采用多文件的開發(fā)。也就是說，為了使程序簡(jiǎn)練，把一些需要重復(fù)利用的代碼寫到.h 的文件里面。五、代碼實(shí)現(xiàn)：#include "stdafx.h"#include <iostream>#include <map>#include <stack>#include <sstream>#include <stdio
