Study Notes
What is an Array?
- A collection of elements, each identified by an index or key
- A data structure that stores a fixed-size, homogeneous collection of elements
- Each element is of the same data type
Characteristics of Arrays
- Fixed size: The number of elements in an array is fixed at creation time
- Homogeneous: All elements in an array are of the same data type
- Indexed: Each element is identified by an index or key
- Random access: Elements can be accessed directly using their index
Operations on Arrays
- Indexing: Accessing an element by its index
- Assignment: Assigning a value to an element at a specific index
- Traversal: Iterating over the elements of an array
- Searching: Finding an element in an array
- Sorting: Arranging elements in a specific order
- Insertion: Adding a new element to an array
- Deletion: Removing an element from an array
Types of Arrays
- One-dimensional array: A single row or column of elements
- Multi-dimensional array: A collection of two or more one-dimensional arrays
- Jagged array: An array of arrays, where each sub-array can have a different length
Arrays in Programming Languages
- Static arrays: Arrays with a fixed size that is determined at compile time
- Dynamic arrays: Arrays that can grow or shrink in size at runtime
- Array operations: Many programming languages provide built-in support for array operations, such as sorting and searching
