How to "hello world"? - Overclock.net

mattc9305 · 3 Weeks Ago

I want to get into basic computer programming and thought "hello world" would be a good start". Are there any tutorials out there on how to do it.

Thanks.

But first what language are you going to program in?

I can do nothing but recommend AutoIt3 as a first language, it's incredibly good to start off with.

There are alot of tutorials spread over the net if you have found the language you would like to use already.

You should realize there is no 'one way' to 'hello world'. It's not a verb - it's a commonly used introduction to a programming language.

For example, with Java, it's

System.out.print("Hello World");

(The S in System is bolded because Java's case-sensitive in its actions. Semi-colons are to indicate the end of a line, and if you forget one in a large-ish block of code, it's annoying to pin-point where you messed up. Don't forget the semicolon!)

Though, in Java, there's a few other things needed to get to the point where you can actually start using functions like that.

If you want to learn how to code, I'd recommend starting with Java, and perhaps moving to C++ or C# after you're familiar with it (Java's sort of based off of C). You might be tempted to go with 'easier' languages like Perl or Python, but it's good learn the more verbose/difficult languages first.

lol.

From what you can see in my example, there are tons of minute details with programming, and not everyone can sit down and have a productive programming session. It takes a certain breed of people to learn something as abstract as code and build something with it. It's not legos, y'know

.

There are online tutorials on Java and C and Python and such, but I'd recommend getting a book like Head-First Java if you're serious about getting into coding.

if you are interested in C++, which is a very good first language to learn, here are a few things to get you going!

Quote:

#include <iostream>
using namespace std;
int main()
{

cout << "Hello World!" << endl;

}

Im pretty sure thats right, I am going off memory but I think it depends on your compiler. We were taught C++ in Linux, it might be different from compiler to compiler and os to os, i know that my C++ book is different than what we were taught in class.

Basically the first 3 lines are common to basic codes until you start hitting more complex mathematics, loops and more complex programs in general.

{ opens when code where as } closes it

Cin is the data being input
Cout is what the program outputs
endl is the end of a line....

Someone correct me if I made a mistake =)

this is whati had to do in my programming class on the 2nd day of school. the title was hello world and we used Windows Visual Studio 2005 C++

Personally I would recommend Pascal as a first language (Or Delphi as i think it is now known - someone will correct that if I'm wrong

).

My reason?
Well, Pascal was primarily designed to TEACH programming... So that's a no-brainer from the start.

It will also (If you have the right mindset) get you to think about encapsulation and "Object Oriented Programming" which, imho, is a "good thing".

There are literally thousands of online tutorials for pascal/delphi.

Whatever you do as a beginner, I would suggest ignoring the "visual" aspect of coding; Yes it can make you a nice window interface in which to "drop" your buttons etc, but you will lose-out on the fundamentals of coding if you use a visual-ide language like VB.

I tried to learn with C++ and found it to be very difficult... but thats just me lol. So I went Pascal---Java.

Either way, enjoy your learning and congratulations for taking the step.

Reason I say that is that Software is the most complex thing (to date) that mankind has ever created... Vastly more complex thatn the hardware to which it speaks.

Code:

#include <iostream>
#include <stdio.h>
using namespace std;

int main()
{
    printf("Hello world!");

    return 0;
}

I believe that's how it's done in C++. Never did that, (hello world junk) but that's the basics to writing c++ so why not...

Dont reply if you dont know any more than the OP. It simply isnt helpful.

The code was C in a C++ env. Why? I dont know, no use.

Pick a language. Dont make it java, and dont make it something old like Pascal or Delphi.

Python/Perl are good scripting langs, or C/++ is good for a compiled language. Youll have much more power with it.
