Question

Write a program to find the series:
1+1/3+1/5+.................................+1/20

Answer 1

import java.util.*;

public class Series

{

public static void main(String args[])

{

Scanner in = new Scanner(System.in);

int a=0,i;

for(i=1;i<=20;i=i+2)

{

a=a/i;

System.out.println("Display the series"+a);

}

}

}

Answer 2

// C++ program to find sum of series

#include <iostream>

using namespace std;

// Function to return sum of

// 1/1 + 1/2 + 1/3 + ..+ 1/n

class gfg

{

public : double sum(int n)

{

double i, s = 0.0;

for (i = 1; i <= n; i++)

s = s + 1/i;

return s;

}

};

// Driver code

int main()

{

gfg g;

int n = 5;

cout << "Sum is " << g.sum(n);

return 0;

}
