C Program to evaluate the series sum=1-x+x^2/2!-x^3/3!+x^4/4!……-x^9/9!

				
					#include<stdio.h>

int main() {
  int n, i, j, fact = 1;
  float sum = 0;
  printf("\n Enter Value of n : ");
  scanf("%d", & n);
  for (i = 1; i <= n; i++) {
    fact = 1;
    for (j = i; j > 0; j--) {
      fact = fact * j;
    }
    sum = sum + (1.0 / fact);
  }
  printf("\n Sum of Series = %f", sum);
  return 0;
}
