C实例 创建一个简单的链表
#include <stdio.h> #include <stdlib.h> struct node { int data; struct node *next; }; struct node *head = NULL; struct node *current = NULL; //display the list void printList() { struct node *ptr = head; printf("\n[head] =>"); //start from the beginning while(ptr != NULL) { printf(" %d =>",ptr->data); ptr = ptr->next; } printf(" [null]\n"); } //insert link at the first location void insert(int data) { //create a link struct node *link = (struct node*) malloc(sizeof(struct node)); //link->key = key; link->data = data; //point it to old first node link->next = head; //point first to new first node head = link; } int main() { insert(10); insert(20); insert(30); insert(1); insert(40); insert(56); printList(); return 0; }
