Thread Rules
1. This is not a "do my homework for me" thread. If you have specific questions, ask, but don't post an assignment or homework problem and expect an exact solution.
2. No recruiting for your cockamamie projects (you won't replace facebook with 3 dudes you found on the internet and $20)
3. If you can't articulate why a language is bad, don't start slinging shit about it. Just remember that nothing is worse than making CSS IE6 compatible.
4. Use [code] tags to format code blocks. |
Nevermind....I just overlooked an obvious mistake because of where the error was pointing.
guess Ill be a frequent question asker on here, but again diff problem (not fully finished with it ) but I am not understanding the error I receive when running it.+ Show Spoiler +import javax.swing.JOptionPane;
public class payroll{
public static void main(String[] args) {
String nameString = JOptionPane.showInputDialog(
"What is your name: ");
String payString = JOptionPane.showInputDialog(
"Enter your hourly pay: ");
double pay = Double.parseDouble(payString);
String hoursString = JOptionPane.showInputDialog(
"Enter number of hours worked in a week: ");
double hours = Double.parseDouble(hoursString);
grosspay = (hours * pay)
String federalString = JOptionPane.showInputDialog(
"Enter federal tax withholding rate: ");
String stateString = JOptionPane.showInputDialog(
"Enter state tax withholding rate: ");
System.out.println("\t" + "Employee Name: " + nameString + "\n"+
"\t" + "Hours Worked: " + hoursString + "\n" +
"\t" + "Pay Rate: " + payString + "\n" +
"\t" + "Gross Pay: " + grosspay );
}
}
Error is on String federalString line says expects a ;.....line is the same as all other lines so not sure really what the problem is thanks a bunch guys.

grosspay = (hours * pay) is missing a ;
Errors are not necessarily at the same line the compiler is saying. They might be earlier, or even later.

Hey guys, I'm going to start college this fall and I'm planning on majoring in Computer Sciences. I've already enrolled, but when I talked to my advisor she said my first actual class in the major, Fundamentals of Software Design, uses a lot of Java, is very fast paced, and can sometimes jump around, assuming you already know the basics of programming.
Since I've never taken an actual programming class and have only been casually messing around with Visual Basic (trust me, I know), I know all of nothing about actual programming, I was wondering where I could read up this summer about some general concepts of programming and maybe some introduction to Java specifically? Some universities have good CS lectures online. Here's a Stanford introductory CS lecture series using Java for example: CS106A. IIRC you can find the class website for this course with most/all of the resources you might need to go through the course as if you were a student. Wow that's really cool, thanks a lot for sharing.

Hi everyone! I'm interested in getting into and trying out programming to see if it would be a viable job later on and if I should consider cs in college. However, I am a complete novice to programming. I've messed around with html on w3schools but it seems kinda easy and remedial so I tried learning java/C++. I think those might be a little difficult for me though so I'm asking you all to help me pick a language or something to get my foot into the door of programming. Thanks! Also links to guides are much appreciated since google likes to give me paid ones :/.

Python is a very easy beginner language and also very useful skill to have in the future. The official docs are great tool for learning. They have a very easy to follow tutorial. Get started here:

Hey all, looking for someone with experience in any of the following to help me out a bit:
CCXML
VXML
Nortel Media Processing Server (MPS)
IVRs (Interactive Voice Response)
PeriPro
Pretty much I got student position that involves porting current IVR programs on the MPS from PeriPro to VXML. I have never worked in PeriPro or VXML, but I have an XML background. They are giving me time in the job to learn these languages so its not terrible, but i have a few questions.
PM or post <3

Has anyone here heard of Nemerle? http://nemerle.org/about
I've been checking this language out for the past couple of days, and so far it's a to the maz amazing. It's got the best type inference system to date, with optional static typing for performance in commercial products. This allows for rapid development with the dynamic typing, but the performance and safety of static languages.
It has the ability to create macros, something that hasn't been implemented well since lisp, really. These macros are so powerful, they can add language wide functions without the hassle of creating a new source file in each program you start. They can also be used to add new syntax to programs, for example.
+ Show Spoiler +
macro forp (i, n : int, m : int, body)
syntax ("forp", "(", i, "in", n, "to", m, ")", body)
This, Pythons for i in range(n), can be used as
forp (i in 3 to 10) Nemerle.IO.printf ("%d\n", i)
which will print 3, 4, 5, 6, 7, 8, 9, 10
This language also has metaprogramming, which we can all agree is really helpful. For all who don't know what it is, it's basically generating xml files, or other data languages at compile time through the language itself, instead of writing it ourselves as programmers.
It is a multi-paradigm language, supporting both OOP as strong, if not stronger, than C# and Java, along with functional programming as powerful as Haskell. You can create domain specific languages using macros compiled into dlls, which adds DOP and LOP to the list. So, that's 6 paradigms, all as strong as those in languages that are based around it.
It is a .net language, meaning it can run on Windows phone 7, as well as use all .net libraries. It also has Nemerle on rails, which is RoR with static typing. It can also use LINQ, and don't we all love LINQ.
So, as can be seen from my post, I think that this is a big thing. Who am I? I'm a random 15 year old programmer. What is this? The next big language.

After reading the about page and reading a little more into the language i don't see anything special about it. It's another of those "let's take all good languages we know, mix them together, remove the parts that we don't like (i.e. the good parts) and say we are a 'multi-paradigm language'".
It's basically simplified C#, except that it's the default there to declare any variable with "var whatever = ..." (though they renamed var to def so it's not too obvious while also removing the "new" keyword). The macros and meta-programming are ok but don't actually add anything to the language and just support badly designed code (inline XML... seriously? horrible example) and the functional extensions - while nice - don't add much to what C# already has while not really integrating nicely into the other code.
Well, maybe i'm too much a fan of classic C/C++ and defining everything very strictly with a very clean design... and i probably have seen too much bad code, bad design and bad macro abuse...

I hate weakly typed languages so much D:

On the other hand python also does some weird ass shit that makes it hard to use at times...
in all likely hood you won't run into any of this for quite some time if you're just starting up now but I feel like its important to thow in with all the praise python gets as a fantastic intuitive language that it also has some super weird convoluted stuff in it...
In particular I've recently noticed (my current job requires me to write a lot of python) that it handles scope very strangely and is messed with stuff.

I agree with the Doxygen comment. It's a really good system that is used by a lot of different languages. At the very least, it's a good starting point to flesh out a robust API. You basically just put a specially formatted comment block before each function / class, and doxygen will handle the rest.
Agree. If a team ensures to document to the standard the parser is looking for, commenting of major blocks will be consistent throughout and then it becomes a matter of "personal judgement" with respect to inline commenting that can be more easily enforced than trying to set your own standards for the codebase as a whole .

Hey I have a quick question, how would I go about making lets say programs for Starcraft 2. I Remember using Chaos Launcher for brood war and I was wondering what language would be good for this if any. I hope its not "illegal" to do this but I was just Curious, if someone could get back to me on this that would be great thanks ^^ Wiener Hut JunioR!

I imagine most of those were written in C or C++. The actual process of making something like Chaos Launcher isn't particularly easy.

Well I would like to know where to start you know, maybe someone could make the chaos launcher for sc2

Assuming you want to interact with the game itself, you need to look into DLL Injection. I wrote a DLL injector for SC2 specifically when I made APMAlert2, but I don't think I have the source uploaded anywhere. If you'd like to see it I can put it somewhere. Its a C# program with a C DLL to do the actual injecting. It wouldn't really work out like ChaosLauncher though because it has no concept of plugins or anything (although a system like that used in Chaos is not that hard to implement).
You have to realize, though, that Warden is a much, much larger issue in SC2 than it ever was in BW. You can get away with a lot (both legitimate in competitive play, and illegitimate) in BW that you can't in SC2. Along with the fact that reversing BW is a much, much simpler process. If you are still trying to make something in that realm even after that disclaimer (I totally can't blame you if you are  ), then I have the source to APMAlert2 up on github: https://github.com/tec27/APMAlert2
Its kinda crappy, and the DirectX hooking could be a lot more robust, but it might help you get started. There's also source for APMAlert for BW linked in my post about that if you search it, which interacts with the game a lot more than APMAlert2.

Wow tec27 thats really impressive, but something like that would be far too advance for me, it would take me prob a year to fully understand the coding, any good places to start off?

I recently completed a exam with similar questions to this. Anxiously awaiting my results but some of those problems are harder than others. Good to know for programming interviews.

If you're looking to get into reverse engineering games and/or hooking and interacting with them, it can be a bit difficult to start in due to the nature of the applications generally developed utilizing that knowledge (namely, game hacks, viruses, rootkits and the like). Thats not to say its not worth learning, just that there is a lot of useless crap out there regarding it and not a lot of useful tutorials, introductions, and documentation.
If I had to recommend a site for content to reference, it would have to be http://www.gamedeception.net/ . The community is rather belligerent and you will almost never get decent response should you decide to ask a question there, but it does have a ton of useful forum posts by people who know a great deal about reverse engineering games and due to their forum policies, it is basically free of hack beggars to get in the way of such information. Be warned though, its pretty much exclusively hacks that violate any sort of spirit of competition. Once you get past that though, its quite useful information.
For projects to start off with and gain more knowledge, you should probably begin by constructing programs to interact with some simpler games/programs. Minesweeper is a pretty good choice, and there are a bunch of tutorials out there dealing with that program in particular (here's one for example: http://www.codeproject.com/KB/trace/minememoryreader.aspx ). Minesweeper's codebase is relatively simple, so it makes a project like that much easier.
If you truly want to move into the realm of modern games, be prepared to develop a good understanding of how classes and OOP are managed at the assembly level. If you don't understand how member functions, virtual tables, etc. work in assembly, then you'll have no hope of doing anything really cool (That's not to say that you don't have a chance if you don't know them now, just that you'll need to devote some time to figuring them out).
Hope that helps and doesn't scare you away
