Why not use F#?
That's a whole lot easier to integrate with your C# projects.
You can even do WPF entirely in F# without any hassle/Haskell!

I know F#, a little bit.
But right now I am getting rid of being "All Microsoft Geek Boy!". I am learning Linux, trying out new flavors of Linux... Currently my choice is
- Ubuntu Studio
- Ubuntu
- openSUSE
So, when I was learning other operating systems, I thought why not learn other frameworks and programming paradigms. I am not learning Haskell for WPF as I am not at all developing WPF these days. I am instead learning functional programming itself. From my research I came to know that LISP, Scala etc. were all easier than Haskell, which provoked me to take Haskell as a challenge. It was a great experience learning Haskell.
No Microsoft based programming for a while... Learning Linux, learning non-Microsoft languages. I mean, there are many frameworks and systems that a programmer must know. After all, there are many already doing the job of "Jimmy Kode[^]" in this world.

It's good to know a bit about everything because every new language or framework gives you a new perspective on the ones you already knew.
For example, knowing Haskell made me really appreciate C# again!

Actually its been awhile since I have programmed in C# or .NET framework. I have been on a tour for C/C++, cross-platform Java, Haskell and Shell programming. IDEs like, Qt, Eclipse (on Linux) and Text editors to write code (without any syntax highlighting) to be compiled using command line compilers and so on.
No doubt, Microsoft has provided us with great tools and languages for programming. Going into native-ness is sometimes pain.

Good luck on the exam !
I find that code example frightening Afzaal Ahmad Zeeshan wrote: I can say I know nothing of C or C++ Well, you said the nothing you don't know well enough on this post to get my up-vote: that's something.

Thank you, Bill! But may I ask, it was "frightening" in the sense of?

Well, learning C at this era is also upto no good. But, it is worth a shot. Using your example, I would be much more interested in the "man inside" rather than the bad cover-up.

Interesting - actually neat - but it would fail, I think if stretched a bit:
int x=5;
a[x] != x[a];
But your discovery is truly wondrous!

Seems to work fine.
#include <iostream>
int foo(int x, int *a)
{
return x[a];
}
int main()
{
int arr[10] = { 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 };
int x = 5;
std::cout << arr[x] << " "
<< x[arr] << " "
<< foo(x, arr) << std::endl;
}
Compiles and runs as expected without warning.

That's unfortunate - I was hoping that the compiler wouldn't accept it because it makes x appear to be an array.
It's not that I don't understand - but one could hope that the compiler would differentiate between the two.

The compiler doesn't do a + 5 , it is worse than that - it does a + 5 * sizeof(5) , so 5[a] becomes 5 + a * sizeof(a) , which is OK, since a is a pointer, and pointers are integers that can be added and multiplied.
Learning something new about Haskell is like buying a new clothes. Learning something new about C/C++ is like discovering the nuclear reaction - it can change you and not always for good. Please, please, don't get twisted, don't go into C/C++ land!

Thanks,
This was the question I used on applicants who claimed (on a scale of 1..10) a level 9 or 10 knowledge of the C language.
Also, I believe a[5] == *(a+5)
Because a[5] gives you the VALUE, not the pointer to the value
The rule as I learned it, is every [] => * level of de-referencing.

Here's my favorite obscure C/C++ array trick, to print hex digits.
std::uint8_t byte
char code[3] = 0;
...
code[0] = "0123456789ABCDEF"[byte >> 8];
code[1] = "0123456789ABCDEF"[byte & 0xf];
std::cout << code;

For the record, this behavior is part of C since K&R. It exists in C++ for backward compatibility. I am not an objective-C guy, but suspect it has same behavior.

I've had to use this knowledge before for an interview. They wanted me to explain how an array could be a constant lookup, and how they worked. This example is extremely good for just being able to understand how an array stores memory and how is accesses it.
