Write a program to generate sum of series 1!+2!+3!+--------------n!

In order generate sum of series 1!+2!+3!+--------------n! there is need to take help of function that can able to calculate the factorial of any number 

Program in C language

#include<stdio.h>

#include<conio.h>

int fact(int n)

{

     if(n==1)

          return 1;

     else

          return n*fact(n-1);

}

void main()

{

     int n,factorial,sum=0,i;

     printf("enter a number \n");

     scanf("%d",&n);

     for(i=1;i<=n;i++)

     {

        factorial=fact(i);

        sum=sum+factorial;

     }

     printf("Sum of the given series is %d",sum);

     getch();

}
