Vectors in C++

In C++, a vector is a dynamic array provided by the Standard Template Library (STL). Unlike regular arrays, vectors can automatically resize themselves when elements are added or removed, making them incredibly flexible for managing collections of data.

In C++, an object is an instance of a class, which is a user-defined blueprint for creating data structures that bundle both attributes (variables) and behaviors (functions).

Think of a class as a recipe, and an object as the actual dish you cook using that recipe.

In C++, an algorithm typically refers to a set of functions provided by the <algorithm> header in the Standard Template Library (STL). These functions help you perform common operations like sorting, searching, counting, and manipulating data structures such as vectors, arrays, and lists.

In mathematics, an algorithm is a step-by-step procedure used to solve a problem or perform a computation. Think of it like a recipe: a clear set of instructions that, when followed correctly, leads to a solution.

Generic programming is a style of programming where algorithms and data structures are written in a way that they can work with any data type. In C++, this is primarily achieved using templates.

In C++, the dot operator (.) and the push_back() function serve very different but essential roles—one for accessing members of objects, and the other for modifying containers like vectors.

The term "arbitrary element" generally refers to any element chosen from a set or container without a specific rule or pattern. In C++, how you work with an arbitrary element depends on the data structure you're using.
