char keyword in C# - GeeksforGeeks

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)); 
    } 
} 

Error:

Too many characters in character literal
