C++

[LeCanard]

Why is C++ so prevalent in finance and has not been replaced by such new languages as C# and Python?

What do you base this comment on?

 

[Polter]

Because folks asking questions like this are too lazy to learn Haskell ;P

And therefore as a stranger give it welcome.

Just a simple and plain answer.
No programming language beats C/C++

watch out CUDA ! Vikings are coming !

Don't forget Clontarf 1014!!!!

C is faster than everything but Fortran. C++ does everything that C# and Java can do but faster. It just takes a lot longer to write efficient code in C++ than C# or Java.

I spend about 50% of my time at work trying to re-factor code written by more experienced actuaries to try to make the code readable and fix it.

Is 'refactor' the same word (euphemism) for fixing a software system that management and developers weren't bothered to get right the first time around?

There are different levels of refactoring: one extreme is a complete redesign.

In some cases you save more time starting afresh instead of wasting thay 50% on sloppy, undocumemented code.

Of course, management will not understand :D

BTW do you like refactoring?

True.
What about COBOL?

C++ also has a lot of well-developed libraries that a person can use to develop their applications without having to write everything from scratch, like Boost (https://www.google-melange.com/gsoc/org2/google/gsoc2014/boostcpp). Or if you don't want to spend the money to buy Matlab, you can interface Octave directly to C/C++ code to do time-intensive operations. And if you want to further increase the speed of your calculations to high-performance computer levels of performance, NVIDIA CUDA supports C language routines.

That said, the best computer language to solve a problem usually depends on the problem. Octave is great for rapid testing of algorithms. C/C++ is great for speed once the algorithm is more stable. And I'm a newcomer to Python, but it seems very well suited to scraping data from web sites.
