C programming for sum of GP series

/*Sum of GP series term by term*/

#include<stdio.h>

#include<math.h>

void

main()

{

            float a,r,s=0.0;

            int n,i;

            printf("enter the value of a,r,n;");

            scanf("%f %f %d",&a,&r,&n);

                        for(i=0; i<n;i++)

                        {

                                    s=s+a*pow(r,i);

                                    printf("\n the sum of the series after %d term is : %f \n",i,s);

                        }

                       

}

/*Sum of G.P series term by term*/

#include<stdio.h>

#include<math.h>

void

main ()

{

                float a,r,s=0.0;

                int n,i;

                printf("enter the value of a,r,n:");

                scanf("%f%f%d",&a,&r,&n);

                for(i=0;i<n;i++)

                {

                                s=s+a*pow(r,i);

               

                printf("\n the sum of the series after %d term is:%f\n",i,s);

}

}

Result:

enter the value of a,r,n:5 0.5 10

 the sum of the series after 0 term is:5.000000

 the sum of the series after 1 term is:7.500000

 the sum of the series after 2 term is:8.750000

 the sum of the series after 3 term is:9.375000

 the sum of the series after 4 term is:9.687500

 the sum of the series after 5 term is:9.843750

 the sum of the series after 6 term is:9.921875

 the sum of the series after 7 term is:9.960938

 the sum of the series after 8 term is:9.980469

 the sum of the series after 9 term is:9.990234
