用C语言编写的订票系统,功能都能实现,附有源码和可执行文件

#include "HeadMain.h"

int ClSave()
{
	struct Client* CPtr;
	FILE* fp;
	if(!CHead)
		return 0;
	CPtr = CHead;
	if(!(fp = fopen("Client.data", "w+")))
	{
		OpenErr();
		return 0;
	}
	while(CPtr)
	{
		fprintf(fp, "%d %s %s %s %d\n", 
			CPtr->Num, CPtr->ID, CPtr->Name, CPtr->LID, CPtr->Amount);
		CPtr = CPtr->Next;
	}
	fclose(fp);
	return 1;
}
