用整型数组存放一个不超过30位的整数?什么意思?

程序有点出错,但不知是不是这样?

看看这个代码：

system("clear");
zero=0;
printf("\nInput the number( -1 to exit):");
scanf("%d", &n);
printf("%d\n", n);
if(n<=-1)
{
delete []a;
return 0;
}

for(i=2; i<=n; i++)
{

for(j=zero; j<len; j++)
{

if((!t)&&(j-zero==1)) ++zero;
}
while(g)

}
}

printf("%d", a[len--]);

//pause();

}
delete [ ]a;

return 0;
}
