#include <stdio.h>

int main (void)

{

     int n;

     long int fact;

     long int sum;

     int i, j;

     //Input number of terms

     scanf ("%d", &n);

     printf (Series: );

     //Calculate the sum of series

     sum = 0;

     fact = 1;

     for (i = 1; i <= n; i++)

     {

          fact = 1;

          for (j = 1; j <= i; j++)

               fact = fact * j;

          sum = sum + fact;

     }

     //Print result

     printf ("Sum of Series: %ld", sum);

Output

Input number of terms: 10

Sum of Series: 4037913
