二十五岁时我们都一样愚蠢、多愁善感，喜欢故弄玄虚，可如果不那样的话，五十岁时也就不会如此明智。

C示例找到单链表大小的程序
#include <stdio.h> #include <stdlib.h> struct node { int data; struct node *next; }; struct node *head = NULL; struct node *current = NULL; //Create Linked List void insert(int data) { // Allocate memory for new node; struct node *link = (struct node*) malloc(sizeof(struct node)); link->data = data; link->next = NULL; // If head is empty, create new list if(head==NULL) { head = link; return; } current = head; // move to the end of the list while(current->next!=NULL) current = current->next; // Insert link at the end of the list current->next = link; } void size_of_list() { int size = 0; if(head==NULL) { printf("List size : %d ", size); return; } current = head; size = 1; while(current->next!=NULL) { current = current->next; size++; } printf("List size : %d ", size); } int main() { insert(10); insert(20); insert(30); insert(1); insert(40); insert(56); size_of_list(); return 0; }
