C++ Standard Template Library in Practice - Defining an Allocator

The video tutorial covers the basics of custom allocators in C++, explaining their roles in memory management, including allocation, construction, destruction, and deallocation. It details how to define a minimal allocator and explores allocator behaviors and flags introduced in C++17. The tutorial provides a practical example by creating a debug allocator, demonstrating its implementation and testing it with a vector to observe memory allocation and deallocation processes.

How does the allocator handle memory allocation and deallocation?

What happens when a vector reaches its limit and needs to reallocate memory?

What are the implications of using a custom allocator with standard containers?
