火车票务管理系统一、课题内容和要求设计目标：设计一个火车票务管理系统，用C语言实现。

对该系统的要求如下：需求描述：1.系统功能(1)火车时刻信息录入。

包括车次、日期、起点、终点、开车时间、到达时间、票价。

数据存入数据文件hchsk.dat或hchsk.txt中。

(2)火车时刻信息查询。

按照车次查询按终点查询按起点查询按终点和日期查询(3)统计按终点统计每日的车次数按起点统计每日的车次数2. 系统主界面应有以下功能选项录入火车时刻信息查询火车时刻信息统计火车车次退出注：建议用VC环境开发用户界面。

结果形式：提交程序设计报告和可演示的系统软件二、需求分析系统主界面应有以下功能选项1．录入火车时刻信息2．查询火车时刻信息3．统计火车车次4.退出(1)火车时刻信息录入。

包括车次、日期、起点、终点、开车时间、到达时间、票价。

数据存入数据文件hchsk.dat或hchsk.txt中。

(2)火车时刻信息查询。

按照车次查询按终点查询按起点查询按终点和日期查询(3)统计按终点统计每日的车次数按起点统计每日的车次数二、概要设计void SearchTrainNum();//按照车次查询void SearchToPlace();//按终点查询void SearchFromPlace();//按起点查询void SearchToPlaceAndDate();//按终点和日期查询void CountToPlace();//按终点统计每日的车次数void CountFromPlace();//按起点统计每日的车次数三、详细设计程序的源代码与注释#include<stdio.h>#include<string.h>#include<stdlib.h>void SearchTrainNum();void SearchToPlace();void SearchFromPlace();void SearchToPlaceAndDate();void CountToPlace();void CountFromPlace();void Star();struct TRAIN{char trainNum[10];char date[30];char fromPlace[20];char toPlace[20];char inTime[30];char outTime[30];double price;};struct TRAIN train[30];int main(){int request;char ch='Y';int i=0;double myprice;FILE *fp;repeat:Star();printf("火车管理系统界面\n");printf("1.录入火车时刻信息.\n");printf("2.查询火车时刻信息.\n");printf("3.统计火车车次.\n");printf("4.退出.\n");Star();printf("\n");printf("请输入:");scanf("%d",&request);switch(request) //利用case分支结构{case 1:{ fp=fopen(".\\train.rec","wb");
