C語言課程設(shè)計--銀行自動存取款機模擬

1、；.作者：周鳴需求分析：本程序設(shè)計的任務為銀行自助存取款機，程序要求實現(xiàn)atm機的基本功能，如 開戶.查詢.存款.取款.轉(zhuǎn)賬.容而生成操作日志。2. 概要設(shè)計：數(shù)據(jù)類型：int，char，F(xiàn)ILE.主程序流程：int main （）1：進入dl()函數(shù)。2：核對輸入賬戶與密碼。3. 核對成功則進入dljm()函數(shù)。4. 選擇操作功能。5. 完成操作，回到功能選擇一欄。6. 可選擇退卡以結(jié)束所有操作。標準函數(shù)名稱和自定義名稱：Void dl ()Void dljm ()Void cx()Void ck()Void qk()Void zz()開始程序 開始程序3. 主程序的流程及各函數(shù)之間的流程關(guān)

2、系。（用圖來描述） 進入dl函數(shù) 輸入賬號 輸入密碼進入dljm函數(shù)選擇atm機功能輸入“100”，退出函數(shù)進入zz函數(shù)進入tk函數(shù)進入ck函數(shù)進入qk函數(shù)進入cx函數(shù)15432#include<stdio.h>#include<stdlib.h>int x,k;void dl();int dljm();void cx();void qk();void zz();void ck();void tk();FILE *fp;FILE *fg;struct atm char name10; int account; short password; float money;at
