Dynamic Array
A dynamic array is a data structure that allows elements to be stored in contiguous memory locations, with the ability to automatically resize itself when elements are added or removed. It provides O(1) access time for elements by index, similar to a static array, but handles memory allocation dynamically to accommodate varying numbers of elements. This makes it a fundamental building block in many programming languages and applications where the size of a collection is not known in advance.
Developers should learn and use dynamic arrays when they need a collection that can grow or shrink efficiently during program execution, such as in scenarios involving user input, data processing, or caching. They are particularly useful in algorithms and data structures where random access is required, like in implementing lists, stacks, or queues, as they offer a balance between flexibility and performance. Understanding dynamic arrays is essential for optimizing memory usage and avoiding common pitfalls like buffer overflows in low-level programming.
