用递归求阶乘：

#include<stdio.h>

int factorial(n);

int main()

{

   int n;

         scanf("%d",&n);

         printf("thefactorial of n is %d.\n",factorial(n));

         return0;

}

int factorial(int n)

{

        

         if(n>1)

                   returnn*factorial(n-1);

         else

                   return1;

}
