C語言 建立 輸出 插入 刪除 修改功能的單項動態(tài)鏈表【最新】

C言鏈表類題目寫函數(shù)一個有三名學(xué)生數(shù)據(jù)的有建立輸插刪除修功能的單項動態(tài)鏈表，很全面，各種測試都試過了，環(huán)境VC6.0結(jié)構(gòu)體為學(xué)號成績struct{num;floatstructnext;struct*pre;};intn=0;structcreate(void){structstruct*tail;struct*pre;struct*p;head=NULL;pre=NULL;p=(structStudent*)malloc(sizeof(structprintf("輸入用戶名和得:\n");if{NULL;}while(0!=p->num){ifhead){head=p;pre=NULL;=NULL;}{pre=tail;}p=(structStudent*)malloc(sizeof(structprintf("輸入用戶名和得:\n");scanf("%ld%f",&p->num,&p->score);}if{}head;}voidprint(structStudent*head){structifp){printf("鏈表中還沒有數(shù)\n");}(p{}}struct*del(structStudentlongnum){struct=head;struct=head;ifhead){NULL;}ifhead->next){if{n--;NULL;}{head;}}if{n--;head;}if{if{n--;head->next=NULL;head;}}head->next;(p1!=NULL){ifp1->num){n--;ifp1->next){=NULL;}{=}}}head;}struct*alter(struct*head,longnum,{struct*p=head;{if{=score;}}head;}struct*insert(structlongscore){structstructstruct*p;p=(structStudent*)malloc(sizeof(struct==score;ifhead){head=head->next=NULL;head;}ifhead->next){if{head->next=p;p->next=NULL;head;}{p->next=head=head;}}if<{p->next=head=head;}p1=head->next;(p1!=NULL){ifp2->num){ifp1->num){p->next==}{ifp1->next){=p->next=}}}}head;}int{struct=create();num_insert;floatfloatprintf("\n\n\n");printf("下為輸出結(jié)果：\n\n");print(head);printf("\n");printf("有節(jié)點%個n",n);printf("\n");printf("面開始刪除節(jié)點\printf("輸入要刪除的節(jié)點號:");head=printf("下為輸出結(jié)果：\n\n");print(head);printf("\n");printf("有節(jié)點%個n",n);printf("面開始插入節(jié)點\printf("輸入要插入的節(jié)點號碼和得:head=printf("下為輸出結(jié)果：\n\n");print(head);printf("\n");printf("有節(jié)點%個printf("面開始修改節(jié)點\printf("輸入要修改的節(jié)點號碼和要改成的得分:head=alter(head,num_alter,score_alter);printf("下為輸出結(jié)果
