Everyone uses dynamic memory in C++, but what is the performance cost that we are paying which we might be unaware of?

In this lecture we will talk about the performance aspects of using dynamic memory, more specifically:
* Allocating and deallocating memory: programs allocating and deallocating many objects can experience slowness because of memory allocation and deallocation.
* Memory access speed: sometimes, the bottleneck is related to how we arrange data in memory or the memory access pattern.

We will provide information on the reasons why the usage of dynamic memory is slow with examples and propose solutions or workaround to make it faster.
