Answer 1

Answer:

#include <stdio.h>

 

double sumseries(double);

 

main()

{

   double number,sum;

   printf("\n Enter the value:  ");

   scanf("%lf", &number);

   sum = sumseries(number);

   printf("\n Sum of the above series = %lf ", sum);

}

 

double sumseries(double m)

{

   double sum2 = 0, f = 1, i;

   for (i = 1; i <= m; i++)

   {

       f = f * i;

       sum2 = sum2 +(i / f);

   }

   return(sum2);

}
