readfile.c

很有用的一个图书管理系统方面的源代码！不用改错直接运用

//#include "Struct.c"


//-----------------------添加代码；包括读图书主文件，书名索引链头文件，书名所以链表文件，作者索引链表文件，出版社索引链表文件,读读者文件，读借还书文件//
void readfile()
{
	FILE *fp;
	if((fp = fopen("Txj","rb+")) == NULL)
		{
			if((fp = fopen("Txj","wb+")) == NULL)
			{
				printf("无法建立文件!\n");
				system("pause");
			}
			
		}
	fread(&a,4,1,fp);
	fread(&i,4,1,fp);
	fread(&p,4,1,fp);
	fread(&q,4,1,fp);
	fread(&r,4,1,fp);
	fread(&s,4,1,fp);
	fread(&t,4,1,fp);
	fread(book,4*a,1,fp);
	fread(Dbasehead.BookDbase,84*i,1,fp);
	fread(IdxFile.BnoIdx,16*i,1,fp);
	fread(File4.ReadRec,20*p,1,fp);
	fread(File5.Bbook,32*q,1,fp);

	fclose(fp);
