Chapter 5, Problem 10E

Explanation of Solution

Recursive method to find sum of series:

Program:

/**********************************************************

* This program demonstrates functionality of recursive    *

* function to compute sum of series                       *

**********************************************************/

//Include header files

#include <iostream>

using namespace std;

//Function prototype

double Recursive_Sum_seri(int n);

The “main()” function reads an integer number from user and call recursive function to find sum of given series.

//Program begins with main function

int main()

{

  //Declare variable

  int n;

  //prompt and read 2nd number from keyboard

  cout<<"Enter a number: ";

  cin>>n;

  //call recursive function

  cout<< "Sum of series is: "<<Recursive_Sum_seri(n);
