Arrays in C#

Initialization and Types

In C#, arrays are fundamental data structures used to store a fixed-size collection of elements sharing the same data type. When declared, arrays are automatically initialized with default values, which are typically 0 for numerical types and null for reference types.

There are two primary types of arrays in C#: rectangular arrays and jagged arrays. Rectangular arrays, denoted by [,], are multi-dimensional arrays with a fixed number of dimensions. On the other hand, jagged arrays, denoted by [][], allow each element to be an array of varying length, offering more flexibility in organizing data.

Implicit Typing

C# introduced implicit typing for arrays in version 3.0 with the var keyword. Implicit typing enables developers to declare arrays without explicitly specifying the data type, enhancing code conciseness and readability. By using var, the compiler deduces the type based on the initialization, simplifying array declarations.
