language features!

[Sean]

Hi, guys:
I am newbie to the C++ from the C. I want to know something about the
C++ language features! Could you describe your two favorite features in
the C++ language and why you like them so much. Also describe the two
features of the C++ language that you think are the most over-rated or
the most misused, and why you think that is the case.
Thanks in advance!

Hmmm, this question sounds quite familiar....
.... googling...

Hah, I knew it:
http://groups.google.com/group/comp.lang.c++/browse_thread/thread/8106cb29a63feb75/c4705744d465c4ec

I'm wondering if this is some kind of homework question that will come up
here once every semester or so.

The STL library is by far the most useful C++ feature. This often
makes use of operator overloading and functors, and by definition is a
template library. So my vote goes to those features for the most useful.
The most frequently misused operations are new and delete resulting
in failed garbage collection, hence I recommend using the STL containers
instead. Finally, the parsing of class objects by value is common source
of problems due to constructor/destructor implementation.

There are so many of C++ features it is just unfair to mention only
two...but if you must then:

* function and operator overloading
* // comment

So you can write something as cool as:

Vector rotate(Vector v, Vector center, double theta)
{
Vector r = v - center; // operator overloading
Vector p = polar_form(r);
r = rectangular_form(p + J(theta));

return center + relative;
}

I find this question kinda ugly. My two favorite features?

Amen, JB. Without STL, I can't imagine myself using C++ at all. I've
also become rather boost-dependent (www.boost.org) as well. Some really
amazing stuff in there.

This is school related, right? Well, if you want to really impress
your teacher, just tell him that the Library for Standard Data is what
you use all the time. It will be replacing the STL. So, in class one
day, just tell your teacher that you use the LSD all the time, and see
how impressed he is.
