程序代码：

#include<stdio.h>
void main()
{
    char *point;
    long int b_addr,e_addr,i,j;
    printf("please enter the beginning and end addr in hex\n");
    scanf("%lx%lx",&b_addr,&e_addr);
    for(i=b_addr;i<e_addr;i+=16)
    {
        printf("%05lx:",i);
        point=(char*)i;
        for(j=0;j<16;j++)
        {
            if(j==8)
                printf(" ");
            printf("%02x\t",*point);
            point++;
        }
        printf("\n");

    }
}
