Question

Write the code in C#

List the evens or the odds. You are given a lower and an upper bound for a range of integer numbers. Then a command specifies if you need to list all even or odd numbers in the given range.

Answer 1

using System;

public class SequenceEvenOdd
{
    public static void Main(string[] args)
    {
        Console.Write("Enter upper bound: ");
        int upper = Convert.ToInt32(Console.ReadLine());
        Console.Write("Enter lower bound: ");
        int lower = Convert.ToInt32(Console.ReadLine());
        Console.Write("Do you want to display even or odd? ");
        bool odds = Console.ReadLine().Equals("odd", StringComparison.OrdinalIgnoreCase);
        for (int i = lower; i <= upper; i++)
        {
            if (odds && i % 2 == 1)
            {
                Console.WriteLine(i);
            }
            if (!odds && i % 2 == 0)
            {
                Console.WriteLine(i);
            }
        }
    }
}
