[C++知识库]单链表 的创建（头插法）与打印

#define LEN sizeof(struct Node)
typedef struct Node{
	int data;
	struct Node * next;
}node;//定义结点的类型;
 void createLink(node * head, int *a, int n){
	 
	 head->next = NULL;
	 for (int i = 0; i < n; i++){
		 node * p = (node*)malloc(LEN);
		 p->data = a[i];
		 p->next = head->next;
		 head->next = p;
	 }
}

 void pri_link(node *head){
	 node *p = (node *)malloc(LEN);
	  p= head->next;
	 while (p != NULL){
		 printf("%d\n", p->data);
		 p = p->next;
	 }

 }
 int main(){
	 int a[5] = { 1, 2, 3, 4, 5 };
	 node * head = (node *)malloc(LEN);
	 createLink(head, a, 5);
	 pri_link(head);
 }

执行效果如下如图
