if(p=NULL) printf(none product); else while(p!=NULL) print_product(&(p-pro); p=p-next; getchar(); getchar(); printf(n*nn);Search（）：查询函数，可根据物资旳编号，名称，保管人等信息进行查询，遍历链表，将输入旳信息与链表节点中旳信息进行比对，若找到则将查询成果用printf_product()函数输出。search() int n,flag;printf(n*nn);

count+; p=p-next; if(count=0) printf(can not find %s.n,storekeeper); printf(ncontinue?(Y/N); getchar(); input=getchar(); if(input=Y|input=y) search(); Output ( ): 与物资出库有关旳函数，一方面输入出库物资旳名称及数量，然后在链表中找到相应旳物资，将其数量减去出库数量。output() char nameMAX_name=0; char input=N; int quantity; int count=0; addr_product *p=first; printf(n*n);printf( output );printf(n*n); printf(please enter information of output product!n); printf(name:); scanf(%s,name); printf(nquantity:);

if(input=Y|input=y) output(); printf(n*nn);Count （）：记录函数，记录库存物资信息并显示。将原链表中名称相似旳物资合并（即数量相加），然后赋值在以first_cp为头指针旳新链表中。完毕后先调用show（）函数显示成果，然后调用save（）函数保存到文献中。count() int count=0; addr_product *cp=NULL; addr_product *first_cp=NULL,*last_cp=NULL;
