Keywords are the words in a language that are used for some internal process or represent some predefined actions. char is a keyword that is used to declare a variable which store a character value from the range of +U0000 to U+FFFF. It is an alias of System.Char.
Syntax:
char variable_name = value;
char keyword occupies 2 bytes (16 bits) in the memory.
Example:
Input: S Output: chr: S Size of a char variable: 2 Input: G Output: Type of chr: System.Char chr: G Size of a char variable: 2
Example 1:
// C# program for char keyword using System;
using System.Text;
class GFG {
static void Main( string [] args)
{
// char variable declaration
char chr = 'S' ;
// to print value
Console.WriteLine( "chr: " + chr);
// to print the size of a char
Console.WriteLine( "Size of a char variable: " + sizeof ( char ));
}
} |
Output:
chr: S Size of a char variable: 2
Example 2:
// C# program for char keyword using System;
using System.Text;
namespace geeks {
class GFG {
static void Main( string [] args)
{
// char variable declaration
char chr = 'G' ;
// to print the type of variable
Console.WriteLine( "Type of chr: " + chr.GetType());
// to print value
Console.WriteLine( "chr: " + chr);
// to print size of a char
Console.WriteLine( "Size of a char variable: " + sizeof ( char ));
// hit ENTER to exit
Console.ReadLine();
}
} } |
Output:
Type of chr: System.Char chr: G Size of a char variable: 2
Example 3:
// C# program for char keyword using System;
using System.Text;
class GFG {
static void Main( string [] args)
{
// char variable declaration
char chr = 'Geeks' ;
// to print value
Console.WriteLine( "chr: " + chr);
// to print size of a char
Console.WriteLine( "Size of a char variable: " + sizeof ( char ));
}
