• Aim: Write a program to evaluate the series sum=1-x+x^2/2!-x^3/3!+x^4/4!......-x^9/9!.
• Code:

  //For turbo C++ remove below comments
  #include <stdio.h>
  //#include<conio.h>
  #include<math.h>
  void main()
  {
      int i;
      float x,sum=0;
      printf("Enter x for series 1-x+x^2/2!-x^3/3!+x^4/4!......-x^9/9! : ");
      scanf("%f",&x);
      for(i=0;i<=9;i++)
      {
          float fact=1;
          for (int j = 1; j <= i; j++){
              fact*=j;
          }
          if (i%2==0)
          {
              sum+=pow(x,i)/fact;
          }else
          {
              sum-=pow(x,i)/fact;
          }
      }
      printf("Sum of series : %f",sum);
      // getch();
  }
