我觉的我的方法比大家简单多了，提交却是WA，有那位高手能指点一下吗?# include <stdio.h>
int main()
{
static char a[102][72]={{"http://www.acm.org/"}},b[8];
int i,j;
for(i=0;;)
{
scanf("%s",b);
if(*b=='Q')
break;
else if(*b=='V')
{
i++;
scanf("%s",a[i]);
printf("%s\n",a[i]);
for(j=i+1;j<102;j++)
*a[j]=0;
}
else if(*b=='B')
{
i--;
if(i>=0)
printf("%s\n",a[i]);
else {i++;
printf("Ignored\n");
}
}
else if(*b=='F')
{
i++;
if(*a[i]!='\0')
printf("%s\n",a[i]);
else printf("Ignored\n");
}
}
return 0;
}
