}
我用这一段运算的结果就只有
求大神教教我

#include <stdio.h>

int main ()
{
    char str [80];
    int i;

    printf ("Enter your family name:Soulie\n");
    scanf ("%79s",str);
    //去掉&，str就是str[0]的地址或者可以改为scanf ("%79s",&str[0]);
    printf ("Enter your age:29\n");
    scanf ("%d",&i);
    printf ("Mr. %s , %d years old.\n",str,i);
    printf ("Enter a hexadecimal number:ff\n");
    scanf ("%x",&i);
    printf ("You have entered %#x (%d).\n",i,i);

    return 0;
}
