Accessors/modifiers naming convention

Is there any kind of naming convention for accessor and modifiers? What I've
been doing is something like this:

// accessor
int getSize();

// Modifier
void setSize( int newsize);

private:
int _size;

Naming conventions are a coding standards concept, which is something
not covered by the C++ standard. I believe the FAQ has links to a few
good ones that you could take a look at.

Sure, a lot of people name accessor/modifier functions this way.

Now *that* isn't allowed. Leading underscores are reserved for the
implementation. I suggest changing that to size_.

Seriously? I've always been taught that you should use leading underscores
for your private variables.

Technically no. Per 17.4.3.1.2/1, identifiers with a leading underscore
and a *LOWER CASE* letter are only reserved in the global and std
namespaces.

Per 17.4.3.1.2/1, identifiers witha leading underscore followed by an
UPPER CASE letter are reserved, period.

In either case, you're better off not using leading underscores at all.

You've been taught wrong. ;-) *Trailing* underscores, however, are a
common practice to indicate private member variables.

Not quite, there is some rules about how to use leading underscores,
and the above does not violate them as per any requirements of
Standard C++. However, it may violate other standards, or some
other convention, and besides, it's easier to not have to remember
the Standard C++ rules, so in short, the above is probably best
avoided, and instead some other convention be used (like trailing _'s)
if indeed some convention at all is necessary.
