G - Arrays
Preq. Programming Basics
Arrays
- Stores a collection of elements of the same data type
- Contiguous block of memory
- Widely used in programming because they allow efficient access and manipulation of a large number of values
- Elements can be accessed using index
- Advantages: Fast insertion, Fast access of elements
- Disadvantages: Slow search, Slow deletion, Fixed size
- Ordered Arrays: Elements are arranged in a specific order based on values
- Advantage: More efficient search algorithm
- Disadvantage: Slow deletion, slow insertion, fixed size
- Arrays are 0 indexed: Index of 1st element is 0, 2nd element is 1
- Index of last element: length - 1
- In Pseudocode, Arrays index might start from 0 or 1
