我写的C语言代码笔记

单链表#include stdio.h #include stdlib.h //实现初始化头插尾插删除输出等单链表的基本操作 typedef struct Node { int data; struct Node* next; }Node; //初始化 Node* intList() { Node* list (Node*)malloc(sizeof(Node)); list-data 0; list-next NULL; return list; } //头插法 void headInsert(Node* list, int data) { Node* node (Node*)malloc(sizeof(Node)); node-data data; node-next list-next; list-next node; list-data; } //尾插法 void lastInsert(Node* list, int data) { Node* node (Node*)malloc(sizeof(Node)); node-data data; node-next NULL; Node* head list; while (list-next) { list list-next; } list-next node; head-data; } //删除一个 void delect(Node* list,int data){ Node* cur list-next; Node* pre list; while (cur) { if (cur-data data) { pre-next cur-next; free(cur); list-data--; break; } pre cur; cur cur-next; } } //删除多个相同 void delectAll(Node* list, int data) { Node* cur list-next; Node* pre list; while (cur) { if (cur-data data) { pre-next cur-next; free(cur); cur pre-next; list-data--; continue; } pre cur; cur cur-next; } } void printList(Node* list) { list list-next; while (list) { printf(%d ,list-data); list list-next; } printf(\n); } int m() { Node* list intList(); headInsert(list,1); headInsert(list,1); headInsert(list, 1); headInsert(list,2); headInsert(list,3); lastInsert(list, 4); // 3 2 1 1 1 4 printList(list); delect(list, 1); printList(list); // 3 2 1 1 4 delectAll(list, 1); // 3 2 4 printList(list); return 0; }
