C#: Calculate n terms of square natural number and their sum

C# Sharp For Loop: Exercise-25 with Solution

Write a C# Sharp program that displays the n terms of square natural numbers and their sum.
The series is as below:

1 4 9 16 ... n Terms

Sample Solution:-

C# Sharp Code:

using System;  
public class Exercise25  
{  
    public static void Main()
{
   int i,n,sum=0;
   
	Console.Write("\n\n");
    Console.Write("Calculate n terms of square natural number and their sum:\n");
    Console.Write("-----------------------------------------------------------");
    Console.Write("\n\n");     
   
   Console.Write("Input the number of terms : ");
   n= Convert.ToInt32(Console.ReadLine());     
   Console.Write("\nThe square natural upto {0} terms are :",n);
   for(i=1;i<=n;i++)
   {
     Console.Write("{0}  ",i*i);
     sum+=i*i;
   }
   Console.Write("\nThe Sum of Square Natural Number upto {0} terms = {1} \n",n,sum);
  } 
}

Sample Output:

Calculate n terms of square natural number and their sum:                                                                                                      
-----------------------------------------------------------                                                                                                    
Input the number of terms : 10                                                                                                         
The square natural upto 10 terms are :1  4  9  16  25  36  49  64  81  100                                                                                     
The Sum of Square Natural Number upto 10 terms = 385
