For the majority of code, even the distinction between stack allocation and cost-free-retail store allocation doesn’t make a difference, nevertheless the advantage and safety of vector does.

Violating this rule would be the number 1 explanation for getting rid of reference counts and discovering your self by using a dangling pointer.

The pointers usually are not a random set of unrelated principles in which you can randomly select and choose by having an expectation of results.
