I think the point is the the OP (Albert) fears that using C++ would
require him to switch completely to Object Oriented programming rather
than the functional programming style that is more common in C and
that he has been using for years and that he is familiar and
confortable with.

Personally, I think although one needs to gain an undertanding of C++,
one can keep working in functional programming, close to C style and
gain significant benefits by using the STL.

Oh, I dunno - I seem to get by.

Not quite. In coding contests, everyone I know uses a functional
programming style, it's just that they are about getting the algorithms
right in a limited time, not spending half the time debugging the
various operations/functions for the sometimes tricky data structures
required (eg. height-balanced binary search trees, *maybe* the
heap-based priority queue and the disjoint set operations for
Kruskal's). I'm keeping in mind that at international level (ie. the
IOI), no reference materials can be brought in by people, and the
computers only provide STL docs and C reference.

I don't think "functional programming style" is really what
you mean. A functional programming style is common in Lisp and
similar languages. The most common programming style in C is an
imperative or procedural style.

Yep, you're right; that is indeed what I meant :)
