Keywords are the words in a language that are used for some internal process or represent some predefined actions. byte is a keyword that is used to declare a variable which can store an unsigned value range from 0 to 255. It is an alias of System.Byte.
byte keyword occupies 1 byte (8 bits) in the memory.
Syntax:
byte variable_name = value;
Example:
Input: 250 Output: number: 250 Size of a byte variable: 1 Input: 150 Output: Type of num1: System.Byte num1: 150 Size of a byte variable: 1
Example 1:
// C# program to show the usage of byte keyword using System;
using System.Text;
class GFG {
static void Main( string [] args)
{
// byte variable declaration
byte num = 255;
// to print value
Console.WriteLine( "num: " + num);
// to print size of a byte
Console.WriteLine( "Size of a byte variable: " + sizeof ( byte ));
}
} |
Output:
num: 255 Size of a byte variable: 1
Example 2:
// C# program to show the usage of byte keyword using System;
using System.Text;
class GFG {
static void Main( string [] args)
{
// byte variable declaration
byte num1 = 261;
// to print value
Console.WriteLine( "num1: " + num1);
// to print size of a byte
Console.WriteLine( "Size of a byte variable: " + sizeof ( byte ));
}
} |
Error: When we enter number beyond the range from (0-255).
Constant value `261' cannot be converted to a `byte'
Example 3:
// C# program to show the usage of byte keyword using System;
using System.Text;
namespace geeks {
class GFG {
static void Main( string [] args)
{
// byte variable declaration
byte num1 = 150;
// to print type of variable
Console.WriteLine( "Type of num1: " + num1.GetType());
// to print value
Console.WriteLine( "num1: " + num1);
// to print size of a byte
Console.WriteLine( "Size of a byte variable: " + sizeof ( byte ));
// hit ENTER to exit
Console.ReadLine();
}
} } |
Output:
Type of num1: System.Byte num1: 150 Size of a byte variable: 1
