How the heck can anyone get bored of C++? Like those Java coders, never could understand them.

It's kinda mainstream... Everybody is used to it...

Frankly, C++ is too...procedural. I tried Perl, but prefer Ruby instead. And I agree with Stefy, C++ is as if you are instantaneously doing something you have to, rather then enjoying programming.

In your educational system or at work you will soon enough run into a functional rather than procedural language.

I still prefer other languages over C++.

I prefer functional over procedural. But once you learned procedural first, forever will you think that way.

Have you two ever tried something of the sorts of APL and J?

Hi;

I didn't like APL. Pretty early on I got fascinated by AI so the functional paradigm is where I stayed.

So, you have tried Lisp or Prolog?

Mathematica uses prolog. Maxima uses lisp. I have used lisp for a while.

( * 1 2 3 4 5 ) yields 120

Don't remember all that much about the language but I do remember writing a package to do multiprecision arithmetic in it.

I like creating compression systems. On IDE based languages anyways...

I am very impressed by the shortness of coded that gets written in J. I.e. it takes only 4 characters to sum a matrix +/+/...

But look at the awesome power of lisp

`(mapcar #'+ '(1 2 3 4 5) '(10 20 30 40 50)`

yields (11 22 33 44 55)

or M's power

{1,2,3,4,5}+{10,20,30,40,50} -> {11,22,33,44,55}

No annoying loop. No remembering whether arrays start at 0 or 1. No going past the end of the array.

J can do that too.

```
1 2 3 4 5+11 12 13 14 15
12 14 16 18 20
```

Can J do this?

(Sum[x^k,{k,1,6,1}]/6)^5 //Expand

You must remeber J is neither a mathematical package nor a symbolic manipulator...
