【C語言】課程設(shè)計-ATM機模擬操作(附源碼)(共18頁)

精選優(yōu)質(zhì)文檔-傾情為你奉上C語言-ATM機模擬操作程序?qū)崿F(xiàn)功能點：a. 查詢：查詢帳戶的存款余額。按任意鍵返回主菜單；b. 取款：輸入100、500、1000、2000、5000、其它金額為取款金額，取款金額不超過帳戶余額，操作后帳戶余額應相應減少，之后可返回主菜單；c. 存款：輸入100、500、1000、2000、5000、其它金額為存款金額，存款金額不超過20000元，操作后帳戶余額應相應增加。之后可返回主菜單；d. 轉(zhuǎn)帳：輸入一個帳戶號，程序判斷與文件信息是否相符，儲戶確認無誤后，再輸入100、500、1000、2000、5000、其它金額為轉(zhuǎn)帳金額，轉(zhuǎn)帳金額不得超過帳戶余額，操作后帳戶余額應相應減少。之后可返回主菜單；e. 修改密碼：連續(xù)輸入兩次新密碼(兩次輸入結(jié)果完全相同)后，新密碼取代舊密碼，并存放到帳戶信息文件中。之后可返回主菜單；f. 退出：退出系統(tǒng)；g. 幫助：增加趣味性；h. 存款時，可正可負，正表示存款，負表示取款；i. 帳戶信息存放在accounts.txt文件，儲戶存取款記錄保存在records.txt中；(在目錄下創(chuàng)建這兩個文件)j. 采用模塊化程序設(shè)計方法來實現(xiàn)，即main()顯示主菜單、調(diào)用相關(guān)函數(shù)實現(xiàn)相應功能，起主控作用；k. 儲戶一天內(nèi)輸錯密碼的次數(shù)不能超過3次，否則無法進入系統(tǒng)；l. 有效避免輸入存款金額、取款金額為負數(shù)等異常情況的出現(xiàn)。較為突出的功能是注冊、登錄時賬號密碼的核對驗證；存款轉(zhuǎn)出轉(zhuǎn)入金額的核對。是否超過余額，是否不符合格式，是否為沖突操作。（2）程序運行截圖及說明（每圖限50到100字）；l 進入程序，menu1可選擇登錄、注冊功能。l 選擇登錄，輸入賬號密碼，通過輸入內(nèi)容與文件的匹配，判斷是否成功登錄。若登錄失敗，則重新選擇。l 選擇注冊，輸入賬號密碼，寫入文件中。l 進入menu2,有五大功能選擇，輸入對應的序列號進入。l 余額查詢功能輸出賬號所對應的余額。l 取款功能，需要安裝要求取出格式化的金額。l 存款功能，選擇金額，若超過存款，自動報錯。存儲成功后，在屏幕上顯示余額并可在txt中看到對應數(shù)目的增加。l 修改密碼功能，輸入當前密碼，輸入新密碼，并進行確認。即修改成功。l 轉(zhuǎn)賬功能，輸入對方卡號，核程序核對卡號是否存在，選擇金額轉(zhuǎn)賬，對應存款的減少會反映在屏幕的余額上。l 退出功能，任意鍵退出程序。l 幫助功能，介紹了本程序的相關(guān)信息。（3）采用的主要技術(shù)（限150到200字）；答：主要采用模塊化管理代碼。使用結(jié)構(gòu)體對文本信息進行操作、運用文件操作相關(guān)函數(shù)如fwrite()、fread()、fgets()、fputs()、fgetc()、fputc()、fopen()、fclose().并使用指針操作數(shù)值。附：程序代碼#include<stdio.h> #include<stdlib.h> #include<conio.h> #include<time.h>#include<string.h>#define N 3void enterzhanghao();
