最近在学C语言，没啥说的，直接上代码。

#include <stdio.h>

struct weapon {
  int price;
  int atk;
  struct weapon * next;
};

int main() {
  struct weapon a,b,c, *head;
  a.price = 100;
  a.atk = 100;
  b.price = 200;
  b.atk = 200;
  c.price = 300;
  c.atk = 300;
  head = &a; //a的地址
  a.next = &b;
  b.next = &c;
  c.next = NULL;


  struct weapon *p;
  p = head;
  while( p != NULL) {
    printf("%d,%d\n", p->atk, p->price);
    p = p->next;
  }
  return 0;
}
