一、顺序表的创建、删除和插入
#define _CRT_SECURE_NO_WARNINGS 1#include<stdio.h>struct sqlist {int date[10];int length;};void InitList(sqlist& L) {for (int i = 0;i < 10;i++) {L.date[i] = 0;}L.length = 0;}void charu(sqlist& L) {for (int j = 0;j < 5;j++) {scanf("%d", &L.date[j]);L.length++;}}void ListInsert(sqlist& L, int i, int e) {for (int k = L.length;k >= i;k--) {L.date[k] = L.date[k - 1];}L.date[i - 1] = e;L.length++;}void print(sqlist& L) {for (int i = 0;i < L.length;i++) {printf("%d ", L.date[i]);}printf("\n");}void ListDelete(sqlist& L, int i, int e) {for (int j = i;j < L.length;j++) {L.date[j-1] = L.date[j];}L.length--;}int main() {sqlist L;//创建顺序表LInitList(L);//初始化顺序表shuru(L);//输入值ListInsert(L, 3, 3);//插入值print(L);//打印ListDelete(L, 3, 3);//删除值print(L);return 0;}
以上操作分别实现了对顺序表的创建，插入，删除和打印
二、单链表的创建、删除、增加和输出
#define _CRT_SECURE_NO_WARNINGS 1#include<stdio.h>#include<stdlib.h>struct ListNode { int num; struct ListNode* next;};struct ListNode* create(struct ListNode* head) { struct ListNode * p1, * p2; p1 = p2 = (struct ListNode*)malloc(sizeof(struct ListNode)); scanf("%d", &p1->num); while (p1->num!=0){ if (head == NULL) { head = p1; } else { p2->next = p1; } p2 = p1; p1= (struct ListNode*)malloc(sizeof(struct ListNode)); scanf("%d", &p1->num); } p2->next = NULL; free(p1); return head;}void print(struct ListNode* head) { while (head != NULL) { printf("%d ", head->num); head = head->next; }}int main() { struct ListNode* head=NULL; head=create(head);//创建链表 print(head);//输出链表return 0;}
以上操作为创建链表并打印，效果如下：
现在增加插入操作
#define _CRT_SECURE_NO_WARNINGS 1#include<stdio.h>#include<stdlib.h>struct ListNode { int num; struct ListNode* next;};struct ListNode* create(struct ListNode* head) { struct ListNode * p1, * p2; p1 = p2 = (struct ListNode*)malloc(sizeof(struct ListNode)); scanf("%d", &p1->num); while (p1->num!=0){ if (head == NULL) { head = p1; } else { p2->next = p1; } p2 = p1; p1= (struct ListNode*)malloc(sizeof(struct ListNode)); scanf("%d", &p1->num); } p2->next = NULL; free(p1); return head;}void print(struct ListNode* head) { while (head != NULL) { printf("%d ", head->num); head = head->next; } printf("\n");}struct ListNode* insert(struct ListNode* head,int i) { struct ListNode* p1,*p2,*p; p1 =p2= head; for (int j = 1;j < i;j++) { p2 = p1; p1 = p1->next; } p= (struct ListNode*)malloc(sizeof(struct ListNode)); printf("请输入插入的数："); scanf("%d", &p->num); p2->next = p; p->next = p1; return head;}int main() { struct ListNode* head=NULL; int a, b; head=create(head); print(head); printf("请输入插入位置："); scanf("%d", &a); head = insert(head,a);//插入新数据 print(head);return 0;}
效果如下：
现增加删除操作
#define _CRT_SECURE_NO_WARNINGS 1#include<stdio.h>#include<stdlib.h>struct ListNode { int num; struct ListNode* next;};struct ListNode* create(struct ListNode* head) { struct ListNode * p1, * p2; p1 = p2 = (struct ListNode*)malloc(sizeof(struct ListNode)); scanf("%d", &p1->num); while (p1->num!=0){ if (head == NULL) { head = p1; } else { p2->next = p1; } p2 = p1; p1= (struct ListNode*)malloc(sizeof(struct ListNode)); scanf("%d", &p1->num); } p2->next = NULL; free(p1); return head;}void print(struct ListNode* head) { while (head != NULL) { printf("%d ", head->num); head = head->next; } printf("\n");}struct ListNode* insert(struct ListNode* head,int i) { struct ListNode* p1,*p2,*p; p1 =p2= head; for (int j = 1;j < i;j++) { p2 = p1; p1 = p1->next; } p= (struct ListNode*)malloc(sizeof(struct ListNode)); printf("请输入插入的数："); scanf("%d", &p->num); p2->next = p; p->next = p1; return head;}struct ListNode* Delete(struct ListNode* head, int i) { struct ListNode* p1, * p2; p1 = p2 = head; while (p1!=NULL&&p1->num != i) { p2 = p1; p1 = p1->next; } if (p1 == head) { head = head->next; } else { p2->next = p1->next; } return head;}int main() { struct ListNode* head=NULL; int a, b; head=create(head); print(head); printf("请输入插入位置："); scanf("%d", &a); head = insert(head,a); print(head); printf("请输入删除值："); scanf("%d", &b); head = Delete(head, b);//删除数据 print(head);return 0;}
效果如下：
因此，我们便实现了对单链表的创建、删除、增加和输出
