A review of pointers and memory allocation covers fundamental concepts in programming related to managing memory in a computer's RAM. Pointers are variables that store memory addresses, allowing indirect access to other variables. Understanding how to allocate and deallocate memory is essential for efficient resource management, especially in languages like C and C++. Memory allocation can be static (predefined at compile time) or dynamic (requested during runtime using functions like malloc and free). Proper memory allocation ensures that programs run efficiently, while improper handling can lead to issues like memory leaks and segmentation faults. This topic emphasizes pointer arithmetic, dereferencing, and techniques to ensure memory is correctly managed and freed when no longer needed.
