vector is one of the most common terms in software development. This guide explains what it means, how it is used in practice, and why it matters, with real examples from the developer world.
Definition
A dynamic array that can grow and shrink automatically. In C++ std::vector is the standard resizable array; in Java it is a thread-safe alternative to ArrayList. In most contexts, vector and dynamic array are synonyms.
