delete automatic int variable
c++, memory-management
Solution
`delete` and `delete[]` should only be used with pointers which you allocated explicitly with `new` or `new[]`, respectively. In particular, for every time you use `new`, you should have a corresponding `delete`. Similarly, each `new[]` needs a corresponding `delete[]`. You should never use either of these with variables for which you do not explicitly allocate memory. The compiler takes care of memory allocation (and deallocation) for all non-pointer variables.
Problem
I am trying to learn the best habits and practices in C++, particularly surrounding memory management. I have been spoiled on this front by using ARC in my iOS apps, and the built-in GC in Java, as well as a few other languages where GC is enabled. I understand that you use `delete` or `delete[]` to deconstruct pointers. My question is, how do you `delete` integers, or other variables of a base data type? My first thought was that since `delete` seems to only work with pointers, can I do this: ``` int intToDelete = 6; delete &intToDelete; ``` So basically, can you create a pointer to an integer in memory, and delete the integer using that pointer?
