[TOC] ## 鏈表創建 ``` #include <stdio.h> #include <stdlib.h> typedef struct node { int data; node* next; } node; node* create() { int i = 0; node* head, *tail, *next; int x = 0; head = (node*)malloc(sizeof(node)); while (1) { printf("Please input your data:\n"); scanf("%d", &x); if (x==0) break; tail = (node*) malloc(sizeof(node)); tail->data = x; if (++i == 1) { head->next = tail; //鏈表只有一個元素，添加到head后面 } else { next->next = tail;//鏈表元素個數>1,把元素鏈接到鏈表尾端 } next = tail; //next指向末尾 } tail->next = NULL; return head; } int main() { node* head = create(); printf("head: %p\n", head); } ```
