C#: Check whether a number is even or odd

C# Sharp Conditional Statement: Exercise-2 with Solution

Write a C program to check whether a given number is even or odd.

Calculating a Even Numbers:

Even Numbers between 1 to 100:

Calculating a Odd Numbers:

Odd Numbers between 1 to 100:

Sample Solution:-

C# Sharp Code:

using System;  // Importing the System namespace

public class Exercise2  // Declaration of the Exercise2 class
{  
    public static void Main()  // Entry point of the program
    {
        int num1, rem1;  // Declaration of integer variables num1 and rem1
        Console.Write("\n\n");  // Printing new lines
        Console.Write("Check whether a number is even or odd :\n");  // Displaying the purpose of the program
        Console.Write("---------------------------------------");  // Displaying a separator
        Console.Write("\n\n");  // Printing new lines
        Console.Write("Input an integer : ");  // Prompting user to input an integer
        num1 = Convert.ToInt32(Console.ReadLine());  // Reading the input integer from the user

        rem1 = num1 % 2;  // Calculating the remainder when num1 is divided by 2

        if (rem1 == 0)  // Checking if the remainder is equal to 0
            Console.WriteLine("{0} is an even integer.\n", num1);  // Printing a message if the number is even
        else
            Console.WriteLine("{0} is an odd integer.\n", num1);  // Printing a message if the number is odd
    }
}

Sample Output:

Check whether a number is even or odd :                                                                       
---------------------------------------
Input an integer : 10                                                                                         
10 is an even integer.
