请问应如何去除此句的warning呢(Dev C++中)?

if (scanf("%d", &x) == NULL)

            warning:comparison between pointer and
 这是“NULL”在不同平台和编译器上面的定义:
 /* A null pointer constant.  */

#if defined (_STDDEF_H) || defined (__need_NULL)
#undef NULL     /* in case <stdio.h> has defined it. */
#ifdef __GNUG__
#define NULL __null
#else   /* G++ */
#ifndef __cplusplus
#define NULL ((void *)0)
#else   /* C++ */
#define NULL 0
#endif  /* C++ */
#endif  /* G++ */
#endif  /* NULL not defined and <stddef.h> or need NULL.  */
#undef  __need_NULL

因此为了去除编译警告,可以显示的加上:

  if (scanf("%d", &x) == (int)NULL);

望采纳!!!
