Types of Arrays:

There are three main types of arrays:

• Single-Dimensional Arrays
• Multi-Dimensional Arrays
• Jagged Arrays

Arrays Type	Description	Example
Single-dimensional Arrays	A linear collection of elements of the same data type.	int[] numbers = {1, 2, 3, 4, 5};
Multi-Dimensional Arrays	Elements arranged in a grid-like structure with multiple dimensions.	int[,] matrix = {{1, 2, 3}, {4, 5, 6}};
Jagged Arrays	An array that holds arrays of different sizes.	string[][] jaggedArray = { new string[] {"A", "B"}, new string[] {"C", "D", "E"} };

Declaring arrays:

To declare an array in C#, you specify the data type of the elements followed by square brackets [] and the array name.

You can specify the size of the array within square brackets, or you can leave it empty for later initialization.

Accessing Array Elements:

Array elements are accessed using zero-based indexing, where the index starts at 0 for the first element.

You access an element by specifying the array name followed by square brackets containing the index of the element you want to access.

Array Initialization:

Arrays can be initialized when they are declared by providing a list of initial values enclosed in curly braces {}.

You can initialize the array elements individually after declaration.

Multidimensional Arrays:

Multidimensional arrays store elements in multiple rows and columns.

To declare a multidimensional array, you specify the data type of the elements followed by comma-separated lengths enclosed in square brackets [,].

Example:

Multidimensional arrays are accessed using multiple indices corresponding to the row and column positions.
