[Dev-C++] Simple SIMPLE C++ q...

[Daniel G. <sp...@ho...>]

If I create a variable, say

int NumberOfDays = 0;

and I decide that I want to delete the variable from memory, how do I do 
this? I don't think I can use delete[] can I, as it's not a pointer. Must I 
create a pointer then call delete? But then how do I remove the pointer?

I'm sure I know the answer to this, but I can't remember!!!

Scope.

If global or static, the variable dies when the application dies,
else it dies whenever it leaves the scope.

Its on the stack and not the heap and will be automatically deleted
when NumberOfDays goes out of scope. If you want control over when the
memory is created and deleted, use a pointer.
