What is Array?

Arrays are fixed-size collections of elements of the same type stored consecutively in memory. Size must be known at compile time and cannot change. Syntax: let arr: [type; size] = [elements];. Example: let nums: [i32; 3] = [1, 2, 3];. Access elements with zero-based indexing: arr[0].
