1+x+(x2/2!)+(x3/3!)+………………………………………+(x^n/n!) Write a program to show the sum of he series when x & n is input through the keyboard.

Source Code :

#include<stdio.h>

#include<math.h>

void main()

{

      int x,n,i,j,fact;

      float sum=1;

      clrscr();

      printf("\nEnter the Value of 'x' : ");

      scanf("%d",&x);

      printf("\nEnter the value of 'n' : ");

      scanf("%d",&n);

      for(i=1;i<=n;i++)

      {

            fact=1;

            for(j=1;j<=i;j++)

            {

                  fact*=j;

            }

            sum=sum+(pow(x,i)/fact);

      }

      printf("\nSum of the Series : %5.2f",sum);

      getch();

}

Output :

Enter the Value of ‘x’ : 2

Enter the Value of ‘n’ : 5

Sum of the Series : 7.27
