Heap memory allows us to create memory independent of the lifecycle of a function. Heap memory starts at low addresses and grows up.

the only way to create heap memory in C++ is with the NEW operator/keyword.

the new operator returns a POINTER to the memory storing the data - not an instance of the data itself.

new always does 3 things:
[1] allocates memory on the heap for the data structure
[2] initializes the data structure
[3] returns a pointer to the start of the data structure
