Signed Byte Array with Example in C#

C# Signed Byte Array: Here, we will find out about the signed byte array in C# – how to announce, how to instate and how to get to components?

Signed Byte Array in C#

In C#.Net, we can make a signed byte array by utilizing sbyte, sbyte is utilized to store both of the qualities (negative and positive) between the scope of – 128 to 127 (Signed 8 bits integer).

It involves 1-byte memory for every component, if the array size is 10, it will take 10 bytes memory.

Statement of a signed byte[]

1) Array statement with instatement

    Syntax:	sbyte[] array_name = { byte1, byte2, byte2, ...};
    Example:	sbyte[] arr1 = { -128, -100, 0, 100, 127};

2) Array statement with fixed number

    Syntax:	sbyte[] array_name = new sbyte[value];
    Example:	sbyte[] arr2 = new sbyte[5];

3) Array declaration with user input

    Syntax:	sbyte[] array_name = new sbyte[variable];
    Example:	sbyte[] arr3 = new sbyte[n];

Getting to signed byte array’s components

Like different sorts of arrays – we can get to the array components with its file, the list begins with 0 and closures with n-1. Here, n is the all outnumber of array components.

Example:

Think about the given example – Here, we are proclaiming 3 arrays with 3 unique methodologies, instating the arrays either with default esteems or client input. To print the array components, we are utilizing foreach loop, we can likewise use for or while loop with loop counter to get to the array components.

using System;
using System.Text;

namespace Test
{
    class Program
    {
        static void Main(string[] args)
        {
            //declaring signed byte[] & initializing it with 5 elements
            sbyte[] arr1 = { -128, -100, 0, 100, 127 };

            //printing all bytes of arr1
            Console.WriteLine("arr1 items...");
            foreach (sbyte item in arr1)
            {
                Console.WriteLine(item);
            }

            Console.WriteLine(); //to print a line 

            //declaring array for 5 elements 
            //reading values and assigning to array 
            sbyte[] arr2 = new sbyte[5];
            //reading values from the user
            for (int loop = 0; loop < 5; loop++)
            {
                Console.Write("Enter a byte (b/w -128 to 127): ");
                arr2[loop] = sbyte.Parse(Console.ReadLine());
            }
            //printing all bytes of arr2
            Console.WriteLine("arr2 items...");
            foreach (sbyte item in arr2)
            {
                Console.WriteLine(item);
            }

            Console.WriteLine(); //to print a line 

            //read value of "n" and declare array for "n" elements
            //reading values and assigning to array 
            Console.Write("Enter length of the array: ");
            int n = int.Parse(Console.ReadLine());
            //declaring array for n elements
            sbyte[] arr3 = new sbyte[n];
            //reading values from the user
            for (int loop = 0; loop < n; loop++)
            {
                Console.Write("Enter a byte (b/w -128 to 127): ");
                arr3[loop] = sbyte.Parse(Console.ReadLine());
            }
            //printing all bytes of arr3
            Console.WriteLine("arr3 items...");
            foreach (sbyte item in arr3)
            {
                Console.WriteLine(item);
            }

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

Output:
