Thread: Ask/Tell about --- Coding. Programming. General script writing.

Coding.... Best tip: Never try to reinvent the wheel. Seriously, if someone did something which works and does not like someone's nightmare in code form, then use it.

C++ is good, but hard. I know it, since I had to program in it (normal software AND graphics programming). Java is okay, used it for networking programs. Other languages include Turbo Pascal and Visual Basic.

I've done some visual basic as well. +=). But my skill level is still at that which is

Do this: ****
Ok...Cool that worked.
Do this: ****
Ok...wait it isn't working....maybe if I cut and paste...Hey that worked...but mine didn't, let me do it again...hey it still isn't working and it is exactly the same!


Lol.

It isn't so much that I want to invent the wheel it is just that it feels like...it feels more like I'm piecing together a puzzle than creating one when I code....even if it is "original" in some respects (since I have done a few original one using pieces of other programs.)

What do you do btw blue?

To be honest, that is what programmers do. They piece together the program with code that works. What is original is then getting all the pieces to work together with as few bugs as possible. It is a weird way of doing things, but it is the reality,

I've learned that since I started...I was put off of the idea originally but now I might as well get used to it. I have an old friend who is a coder from back when coding just started out. She was originally a librarian but then they got a new "toy" and no one knew how to use it so she started playing with it and that started her into coding and now there are lots of businesses that have old systems need her but I think she is retired now...anyway the point of the story is that when I first started thinking about it and I told her that I didn't like coding because it was a lot simpler than I thought it would be she said "people think we walk on water but we just know where the stones are hidden."

I guess what I'm saying is I would like to know why my code is doing what it is doing vs. why the program is doing what it is doing...

(the program does what it does because the code said so...but the code is doing it because the systems says so hehe.)

Coding is fun.

Especially low-level languages like C++ and D, ASM, etc. YOU CAN DO ANYHTING WITH THEM.

What have you done with it Seis?

All kinds of shit.

Mostly just playing around with engines like Irrlicht, or learning APIs like OpenGL, Win32, ALLEGRO, etc.

I do, however, plan on making a full-fledged simulator with C++ w/ ALLEGRO and OpenGL.

I've made games like blackjack games, text adventures, etc.

All in C++.

With DarkBASIC Pro I've made some stuff as well, but I like C++ much more. It's the best language IMO.

I've also screwed about with VB.NET, C#.NET, Java, and ASM.

I'm having troubles with mine right now...no matter what I put in the lines it says "hello world" instead of what I type lol.

Fix it though the cin.get(); command isn't working.

What is your code?

What compiler are you using?

#include <iostream>

using namespace std;

int main()
{
cout<<"HEY, you, I'm alive! Oh, and Hello World!\n";
cin.get();

return 1;
}



Borland C++ Compiler 5.5


It doesn't recognize cin.get as a command so I'm assuming it must not be a part of the language that this one has.

Hrm...

I'm not familiar with Borland C++, but I know its old.

You might want to get a more updated compiler with a more accurate standard.

Try these IDEs:

wxDev-Cpp
DevCpp
Code::Blocks

All use the MinGW Compiler.

just a few things,
avoid using "using"
I know all the tutorials use it, but it can bite you in the arse
(it pulls all the functions and objects into the current namespace, and can lead to naming conflicts)
personally, I think it's really bad practise
but others may say different

but try to get into the habit of fully qualifying object calls
std::cout
(that's 2 colons)

also, use std::endl instead on \n for newlines
\n is an absolutely rigid instruction to the machine to output a linefeed character
and different systems deal with new lines differently
(*nix uses \n, Mac uses \r, Windows uses \r\n)

now, compilers *should* automatically "do the right thing" and interpret the \n to mean whatever the system needs it to mean,
but you're putting trust in the compliance and intelligence of the compiler

the way you've used cin.get() is horrible
you often see this sort of thing on windows programming forums / tutorials as a way of stopping the DOS box from closing automatically
but it's absolutely horrid, and will break your program if you want to use piping or other forms of command chaining

if you don't want your DOS box to close, open a terminal window, and execute your program rather than double clicking it in windows explorer

lastly, you're exiting with 1
if a program finishes with no problems, you should exit with 0
other values are used to indicate a problem

I would rewrite your code as:

Code:

#include <iostream>

int main()
{
  std::cout << "HEY, you, I'm alive! Oh, and Hello World!" << std::endl;

  return 0;
}

I like "using namespace std" rather than using std::

'Using namespace std/ w/e' saves time writing out std:: and minimizes the chance you'll mistype std::cout or cin or whatever you are using.

I'm trying to learn C++, and I'm figuring out the basics without much trouble. The only problem is, I'm not very interested in creating text-only programs, but the tutorial I'm using gives no information about going beyond just using terminal. Where's the best place to find out how to do that?

Also, right now I'm using Microsoft Visual C++ Express edition as my compiler. Is this a good program? Is there a better alternative for Windows XP?

0That's getting into APIs, and Engines, etc. Graphics, that is.

The "basics" are pretty much a small part of the STL, and the language itself.

Everything else is extra.

C++ is hard to learn as a first language. Might I suggest regular C first. C++ is just a superset (for the most part) of C.

Um...no idea if this falls under the same catagory...

But you know anything about html? I have a transparent picture and I want to get the google search engine ontop of it.

I have both the engine and the picture on my webpage but I can only place the engine below, above, or to the sides of the picture. Even if I center it, it doesn't go in the center of the page how I want it. It only centers above or below the picture.

Well I took a class that covered this breifly when I was in 6th grade...as a sub category of general computer knowledge. So I might be able to help you lol. It might be helpful if you give us a link to the webpage or the code you're using.

Other than that all I can say is go here. http://www.w3schools.com/HTML/html_examples.asp

http://nehe.gamedev.net/
that site has loads of incredible openGL tutorials if you're looking for graphics. If you're looking at GUI programs i'm sure there are tons of tutorials online about how to use the windows API.

that's all fine and everything,
but as I said, it *can* bite you in the arse

I can quite happily do:

Code:

#include <yada>

namespace my_app
{
    class cout
    {
        if ( ! check_permissions() )
        {
            throw new exeption::permission_failure;
        }

        if ( ! sanity_checks() )
        {
            throw new exception::unknown;
        }

        log_important_stuff();

        std::cout << cout_value;
    }
}


.......
.......

int main()
{
    #include <standard stuff>
    #include <my_app/cout>

    my_app::cout << "hello";
}

using "using", this will fail horribly

Blue hey, do you think I'll lose anything if I start out with microsoft visual basic?

I decided it would be easier since it gives you free tutorials with download.
