17、;四、测试数据及其结果分析（如图）1.火车时刻信息录入2. 火车时刻信息查询。(1)按照车次查询(2) 按终点查询(3) 按起点查询(4)按终点和日期查询3.统计（1）按终点统计每日的车次数（2）按起点统计每日的车次数4.退出。五、调试过程中的问题编译过程中由于MicrosoftVisualStudioC+6.0编译器的原因。直接给结构体double赋值会出现问题。在金老师的指导和帮助下：程序改为如下：struct TRAIN char trainNum10; char date30; char fromPlace20; char toPlace20; char inTime30; char outTime30; double price;int main() int request; char ch=Y; int i=0; double myprice; FILE *fp;scanf(%s%s%s%s%s%s%lf,traini.trainNum,traini.date,traini.fromPlace, traini.toPlace,traini.inTime,traini.outTime,&myprice);traini.price=myprice;
