具有C编程语言的RAM浏览器

Question

I want to browse a part of the RAM . I tried with this code:

#include <stdio.h>
#include <string.h>

#define MIN ((volatile unsigned char*)0x00000000)
#define MAX ((volatile unsigned char*)0x0000ffff)


main()
{
    volatile char* c;
    for (c=MIN; c<MAX;c++) printf("c[%p]= %c\n",c,*c);
}

However the compiler display this message:

warning: comparison of distinct pointer types lacks a cast.

How I can resolve this problem?

Answer 1

c should have the same type as MIM/MAX : volatile unsigned char* c; .
