Write a C# Sharp program to display the n terms of odd natural numbers and their sums.

 

using System;

public class OddNaturalNumbers {
    public static void Main(string[] args) {
        int n, sum = 0;
        Console.Write("Enter the number of terms: ");
        n = Convert.ToInt32(Console.ReadLine());

        Console.Write("The first " + n + " odd natural numbers are: ");
        for (int i = 1; i <= n; i++) {
            Console.Write(2 * i - 1 + " ");
            sum += 2 * i - 1;
        }

        Console.WriteLine();
        Console.WriteLine("The sum of the first " + n + " odd natural numbers is: " + sum);
    }
}
