Compile it (if you use java) and try it out. It was the second program I had to do. ALL ON MY OWN!!! :D

Congratulations, dude. See, it's not that hard.. :)
 
I got 12 compiler errors :p
Some of the "null" values changed to "nu ll"
Works once I changed them.
 
I consider that a bug... If you type too many characters in code tags, it makes a scroll bar. There is no need to put spaces in long words then...
 
Yay!, I' learning the same kind of programs but in c ++ ! Congrats !
 
MFC scares me I prefer working in C# myself, even if it does away with my beloved pointers, oh pointers how I love thee let me count the ways!

void pWalk = ways;
while(*pWalk != void)
{
pWalk++;
}
int count = pWalk - ways;
 
C# rocks - my housemate stepped me through this windows program I wanted to do, but would have taken too long in C++. I was amazed at how easy it is, and how much stuff there is in .NET. You can download a file in 2 lines, parse it with regular expressions in another 2 lines - quite amazing. Micrsoft rock!
 
Heh yeah though there are times when I want to create simple data-structures, or do some more low level work, that all the managed code makes difficult. But for rapid application development C# and .NET is great. I can imagine it now 30 years down the road when somebody says they are a CS major, I'll sagely say, "Just learn pointers, the rest is easy once you get that" and they will look at me blankly and respond "What's a pointer ?".

Someone that actually thinks Microsoft rocks?
Well... I'll get my VS.NET student license then.

there i cleaned it up for ya :)

sorry, im a perfectionist, couldn't resist
 
D looks very cool. I haven't tried it yet, but it's supposed to be _close_ to stable...

has anyone here tried it?
 
D huh? first time I hear of it. sounds pretty cool :D
 
has garbage collection, OOP, inheritance, operator overloading (hate not having that in java :x), lots and lots of features, compatible with C/C++ binaries I guess, but not backward compatible (code wise) so it is supposed to be rid of all that messy shit in c++
Edit: Messy shit like includes and header files, bad syntax, bad string support, 'pseudo'-typedefs, etc. etc.
 
wow looks very interesting..

might be the new programming language of the future ?

who knows
 
I heard about D a while back. I'm not sure how much support it has, but to be honest C++ has some major improvements coming up so I wonder weather it will ever be picked up.
