题目大意：计算大数的阶乘
要点：数组开大些，，，，，又开小了，wa了一次
ac代码
#include<stdio.h>
int main()
{
int n;
while(scanf("%d",&n)!=EOF)
{
int i,a[100200],c,d=1,tc,j;
a[1]=1;
for(i=1;i<=n;i++)
{
for(j=1,c=0;j<=d;j++)
{
tc=a[j]*i+c;
a[j]=tc%10;
c=tc/10;
}
while(c)
{
a[++d]=c%10;
c/=10;
}
}
for(i=d;i>=1;i--)
printf("%d",a[i]);
printf("n");
}
}
