    Question quick RAM allocation question

    I was wondering something. Is the memory of the variables in a function freed after the function returns? Not static or pointer variables, just something like int number;. I assume it is, but I realized I never actually knew. Just checking. Thanks.

    Yes. Local variables (stack variables) are freed. Pointers, too, are freed, but not what they point at. E.g.:

    void f(){
      int *p = new int[50];
    The actual pointer (probably 4 bytes) is deallocated. The array it points at (probably 200 bytes) is not (which is why you use delete[]).
