当我调用这个函数时，即使它们正在被使用，我也会收到错误消息。有人可以解释一下：

pointers.c:30:5: warning: expression result unused [-Wunused-value]
    *a++;
    ^~~~

pointers.c:39:9: warning: expression result unused [-Wunused-value]
        *s++;
        ^~~~

pointers.c:40:9: warning: expression result unused [-Wunused-value]
        *b++;
        ^~~~

pointers.c:48:7: warning: expression result unused [-Wunused-value]
      *s++;
      ^~~~
