C# Arrays
Duration : 00:02:15
C# Arrays:
Arrays are collections of elements of the same type.Example:
int[] numbers = { 1, 2, 3, 4, 5 };
Single Dimensional Array:
Single-dimensional arrays are linear arrays with a single row/column of elements.Example:
int[] scores = new int[5];
Multidimensional Array:
Multidimensional arrays have multiple dimensions, like 2D arrays (matrices).Example:
int[,] matrix = new int[3, 3];
Jagged Array:
Jagged arrays are arrays of arrays, each sub-array can have a different length.Example:
int[][] jaggedArray = new int[3][];
jaggedArray[0] = new int[] { 1, 2 };
jaggedArray[1] = new int[] { 3, 4, 5 };
jaggedArray[2] = new int[] { 6 };
C# Passing Array to Function:
You can pass an array to a function to perform operations on it.Example:
static void PrintArray(int[] arr)
{
foreach (int num in arr)
{
Console.WriteLine(num);
}
}
C# ‘params’:
‘params’ keyword allows passing a variable number of arguments to a method.Example:
static int Sum(params int[] numbers)
{
int result = 0;
foreach (int num in numbers)
{
result += num;
}
return result;
}
C# Array class:
The ‘Array’ class provides methods for working with arrays, like ‘Sort’ and ‘IndexOf’.Example:
int[] numbers = { 3, 1, 4, 1, 5, 9, 2, 6, 5, 3 };
Array.Sort(numbers);
C# Command Line Arguments:
Command line arguments are values passed when running a program from the command line.Example:
static void Main(string[] args)
{
foreach (string arg in args)
{
Console.WriteLine(arg);
}
}
