What Are Arrays?

An array is a collection of elements of the same type, stored in a contiguous block of memory. Arrays allow you to group related data together and access them using an index.

Example: A list of student grades or names can be stored in an array.

Key Point: Arrays in C# are zero-indexed, meaning the first element is at index 0.
