我如何消除这些警告?

   char foo[10], msg2[100]; 
   int k;
   for (k = 0; foo[k] != NULL; k++) //comparison between pointer and integer
       msg2[k] = NULL; //assignment makes integer from pointer without a cast

感谢。

最佳回答
   int k;
   for (k = 0; foo[k] !=   ; k++)
       msg2[k] =   ;

a. 将体格转换成一个ger变,而不是一个点。 民族解放军是一个协调人。 通常的定义是:

((void *) 0)
问题回答

警告是正确的,你对民族解放军的利用是错误的。

民族解放军是指指点人,而不是用来扼杀绝缘。

Use zero instead of NULL in your code, in BOTH places. If you want a special zero, you may use , but that;s redundant.

*foo = 0;

为了“学习”一种陈词典,你需要做的只是先到零。
