C# Sharp Exercises: Calculate the harmonic series and their sum

C# Sharp For Loop: Exercise-19 with Solution

Write a program in C# Sharp to display the n terms of harmonic series and their sum. The series is :
1 + 1/2 + 1/3 + 1/4 + 1/5 ... 1/n terms

Pictorial Presentation:

Sample Solution:

C# Sharp Code:

using System;  
public class Exercise19  
{  
    public static void Main()
{
   int i,n;
   double s=0.0;
   
	Console.Write("\n\n");
    Console.Write("Calculate the harmonic series and their sum:\n");
    Console.Write("----------------------------------------------");
    Console.Write("\n\n");   
   
   Console.Write("Input the number of terms : ");
   n= Convert.ToInt32(Console.ReadLine());    
   Console.Write("\n\n");
   for(i=1;i<=n;i++)
   {
     Console.Write("1/{0} + ",i);
     s+=1/(float)i;
   }
   Console.Write("\nSum of Series upto {0} terms : {1} \n",n,s);
 } 
}

Sample Output:

                                                                                                                                                               
Calculate the harmonic series and their sum:                                                                                                                   
----------------------------------------------                    
Input the number of terms : 6                                                                                                         
1/1 + 1/2 + 1/3 + 1/4 + 1/5 + 1/6 +                                                                                                         
Sum of Series upto 6 terms : 2.45
