Pointers and References in C++

This lecture covers the fundamental concepts of pointers and references in C++. It starts with a review of pointers, highlighting their importance in sharing objects, choosing unknown elements, and managing objects with extended lifetimes. The lecture then delves into different types of pointers, emphasizing the distinction between pointers and references. It also explores the use of pointers for dynamic memory allocation and the implications of move semantics in C++11. Additionally, the lecture discusses pointers to functions, showcasing how to point to any object, including functions. Examples are provided to illustrate the syntax and usage of pointers to functions in C++. The lecture concludes with a detailed explanation of constant pointers and pointers to constants, clarifying their roles in maintaining object immutability and pointer constancy.
