Arrays, heap and stack and value types
...
LOL, always the nit-picker, Mr. Lippert. :) I feel compelled to point out that with the exception of your latter two cases, the so-called "locals" cease to be locals at compile time. The implementation raises them to the status of class members, which is the only reason they...

What are the differences between a pointer variable and a reference variable in C++?
...s heap. This implies that there is a real address of a reference that the compiler will not tell you.
int x = 0;
int &r = x;
int *p = &x;

assert(p == p2);
You can have pointers to pointers to pointers offering extra levels of indirection. Whereas references only offer ...
When to choose checked and unchecked exceptions
...cal. It just means that we can foresee this error occurring ahead of time (compared with programming errors which cannot be predicted ahead of time). Unpreventable refers to the fact that there is nothing that the programmer can do to prevent the user or other applications from deleting a file betwe...

Matt's explanation is perfectly fine -- and he takes a shot at a comparison to C and Java, which I won't do -- but for some reason I really enjoy discussing this very topic once in a while, so -- here's my shot at an answer.

A private field is usually a better option as the compiler will enforce access restrictions to it, and it will encapsulate the locking mechanism. Usi...
