Arrays are fundamental data structures that allow you to store multiple values of the same data type in a single variable.
🔢ARRAY PROPERTIES AND LIMITATIONS
- Array dimensions are set upon declaration, with lengths determined during instantiation, remaining immutable thereafter.
- Elements in an array are accessed using an index.
- All elements in an array must be of the same data type.
- Accessing an index beyond the array's bounds triggers a runtime exception.
- When passing an array as a parameter to a method, you are passing a reference to the array, not a copy of the entire array.
- Arrays can be single-dimensional, multidimensional, or jagged.
- Unlike lists and other data structures, arrays lack built-in methods for typical operations such as element addition, removal, or sorting
🧩ARRAY TYPES
- Single-dimensional array: An array containing elements arranged in a single line. Accessed using a single index. Represented as a linear collection of elements.
- Two-dimensional array: An array containing elements arranged in rows and columns. Accessed using two indices, one for the row and one for the column. Represents a table-like structure of data.
- Three-dimensional array: An array containing elements arranged in a three-dimensional space. Accessed using three indices, representing depth, row, and column. Represents a cube-like structure of data.
- Jagged array: An array whose elements are arrays themselves. Each sub-array can have a different length. Provides flexibility in representing irregular or non-rectangular data structures.
📦INITIALIZATION
📚ARRAY CLASS
C# offers an Array class to handle various array-related operations. Equipped with methods for creating, manipulating, searching, and sorting array elements, this class serves as the foundational framework for all arrays within the .NET programming ecosystem.
