Write a C program to calculate the following Sum: Sum=1-x²/2! +x⁴/4!-x⁶/6!+x⁸/8!-x¹⁰/10!.

#include<stdio.h>

int main()

{

   float x,i,t,s=1;

   printf(“Enter x value : “);

   scanf(“%f”,&x);

   t=1.0;

   for(i=2;i<=10;i+=2)

   {

      t=t*(-1)*x*x/i*(i-1);

      s=s+t;

      printf(“X = %f\n”,x);

      printf(“t = %f\n”,t);

   }

   printf(“Result = %f\n”,s);

   return 0;

}

Output:

Enter x value : 10

Result = -1296.795532
