C# char keyword

In C#, char is a keyword which is used to declare a variable that can store a character value (Unicode value) value between the range of +U0000 to U+FFFF. char keyword is an alias of System.Char.

It occupies 2 bytes (16 bits) in the memory.

Syntax:

    char variable_name = value;

It can store the character between the range of Unicode +U0000 to +UFFFF.

C# code to demonstrate example of char keyword

Here, we are declaring a char variable chr, initializing it with the value 'X' and printing its value, type and size of a char type variable.

using System;
using System.Text;

namespace ConsoleApplication3
{
    class Program
    {
        static void Main(string[] args)
        {
            //char variable declaration
            char chr = 'X';

            //printing value
            Console.WriteLine("chr: " + chr);
            //printing type of variable
            Console.WriteLine("Type of chr: " + chr.GetType());
            //printing size of a bool 
            Console.WriteLine("Size of a char variable: " + sizeof(char));

            //hit ENTER to exit
            Console.ReadLine();
        }
    }
}

Output

chr: X
Type of chr: System.Char
Size of a char variable: 2
