C# Program to Check Even Number

You are Here:

What are Even Numbers?

An integer (never a fraction) that can be divided exactly by 2. For example, 10 is an even number, i.e., 10 % 2 = 0.

Note: % is a Modulus (Division Remainder) operator, it finds the remainder after division of one number by another. Please check our Arithmetic Operators for more details.

Tips: It is recommended to use our online Even Numbers calculator for better understanding.

Using For Loop

In the following example, we will find all the Even Numbers between 10 and 25 using for loop.

Example

C# Compiler
using System; namespace myApp { class Program { static void Main(string[] args) { int start = 10; int end = 25; Console.WriteLine("Even numbers between {0} and {1}: ", start, end); for(start=start; start<=end; start++) { if(start % 2 == 0) Console.Write(start +" "); } } } }

Using While Loop

In the following example, we will find all the Even Numbers between 10 and 25 using while loop.

Example

C# Compiler
using System; namespace myApp { class Program { static void Main(string[] args) { int start = 10; int end = 25; Console.WriteLine("Even numbers between {0} and {1}: ", start, end); while(start <= end) { if(start % 2 == 0) Console.Write(start +" "); start++; } } } }

Using do while Loop

In the following example, we will find all the Even Numbers between 10 and 25 using do while loop.

Example

C# Compiler
using System; namespace myApp { class Program { static void Main(string[] args) { int start = 10; int end = 25; Console.WriteLine("Even numbers between {0} and {1}: ", start, end); do{ if(start % 2 == 0) Console.Write(start +" "); start++; }while(start <= end); } } }

Even Numbers between any Given Range

In the following example, we will find all the Even numbers between any given range.

Example

C# Compiler
using System; namespace myApp { class Program { static void Main(string[] args) { Console.Write("Enter a (int) starting number: "); int start = Convert.ToInt32(Console.ReadLine()); Console.Write("Enter an (int) ending number: "); int end = Convert.ToInt32(Console.ReadLine()); Console.WriteLine("\nEven numbers between {0} and {1}: ", start, end); for(start=start; start<=end; start++) { if(start % 2 == 0) Console.Write(start +" "); } } } }

Check Whether the Given Number is Even or Odd

In the following example, we will check whether the given number is an Even number or Odd number.

Example

C# Compiler
using System; namespace myApp { class Program { static void Main(string[] args) { Console.Write("Enter a (int) number: "); int num = Convert.ToInt32(Console.ReadLine()); if(num % 2 == 0) Console.Write("{0} is an even number", num); else Console.Write("{0} is an odd number", num); } } }
