Question

Write a program using iterative loop to calculate (numerically) the series:

1/x + 1/x ² + 1/x³ + 1/x⁴ + . . . + 1/xⁿ

Answer 1

#include <iostream>
#include <math.h>


using namespace std;


int main()
{
   int n;
   cout<<"\nEnter n: ";
   cin>>n;
   int x;
   cout<<"\nEnter x: ";
   cin>>x;
   float sum=0;
   for(int i=1;i<=n;i++){
       sum+=(1.0/float (pow(x,i)));
   }
   cout<<"\nSum = "<<sum;


    return 0;
}
