Special considerations for dynamic allocation
Dynamic memory allocation does not come without a cost. In this case, the cost is typically conceptual complexity. This cost also takes the form of added management of heap memory and awareness of the pitfalls of potential memory leaks.
To be honest, I should add that it may take some time to get your head around some of these concepts. For me, some of them took me quite a while to grasp. The best way, I've found, is to take a working program and alter it, see how it behaves, and then understand why it did what it did. Assume nothing. Or, start with a minimal working program that uses the mind-bending feature and then build upon it. Interact with your code; play with it. No matter how you do it, you can't just think about it. You have to twist, poke, prod, and cajole your code until you understand what it is doing. Otherwise, it is just guesswork.
