WAP to Calculate the sum of given Series by using do-while loop or Statement

Statement of C Program: This Program prints the sum of the following Series:

#include<stdio.h>

#include<conio.h>

void main()

{

int n , sign , term_cont;

float term , num , den , sum;

clrscr();

sum=0;

printf(" Enter the number of terms in the series\n");

scanf("%d" , &n);

sign = 1;

num = 1;

den = 1;

term_cont = 1;

do

{

term = (num/den) * sign;

sum + = term;

den ++;

sign* = (-1);                                              /*  sign = sign * (-1)   */

term_cont ++;

} while (term_cont<=n);

printf(" Sum of the series = %f\n" , sum);

}                                                                /* End of main() */

Output:

Enter the number of terms in the series

4

Sum of the series = 0.58

                                                                   That's All
