编程学习网为您整理以下代码实例，主要实现：C语言创建简单链表，希望可以帮到各位朋友。
#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;
}
