Hello World, in C++.

[MaiN]

Like all the others, here we go!

#include <iostream>

int main()
{
std::cout << "Hello world\n";
return 0;
}

The first line, "#include <iostream>" includes the library iostream, which is used later, for the command "std::cout". If we removed it, we would get that "std" isn't an class or namespace, and that "cout" has an undeclared identifier (std).

The next line, "int main()" creates the main function, this function is needed in EVERY C++ program.

Next line, "{" shows where the main() function start.

Next line, "std::cout << "Hello world!\n";
"std" is the identifier for "cout", without "std::" infront of it, we would get a nasty error. We could actually have added "using namespace std;" after "#include <iostream>", and we wouldn't have to use "std::" anywhere in our program. "cout" is used to show something on the screen. "<<" Those two are needed before we show something on the screen, and the next i'm sure you can guess what does. The "\n" part specifies a line-break. Instead of "\n", we could've used "std::cout << "Hello world!" std::endl;" which makes it end the line (endl = end line).
The next line, "}" closes the main() function.
That was the legendary Hello World program in C++.

All that just for hello world? o.0

Yeah, this is one of the reasons I don't like C++. Same amount of code in DB gives a spinning cube, and hello world needs 2 lines.

but then again who the **** needs a spinning cube?

Think it'd be good to add a return 0; at the end aswell. Most compilers will work fine without it (they just assume the program ends after there aren't any more statements), but others require it.

Lololol.... This is an LOL moment LOL MOMENTS!!!!

the reason why C++ is so leet is because how accurate it is, if you can make a spinning 3d cube with four lines of code there proly isnt too much variety in that language.

[**Sweeny**]

If this is for begginers you shouldn't confuse them by shortening the c++ script down you should keep it like
#include <iostream>

using namespace std;

int main()
{
cout<<"Hello World!\n";
cin.get();
}

[MaiN]

Uhmm, your's just as long as mine..
And Reid, you ****ing have to enter a full-screen game-type mode, to even program DarkCode.... Which sucks, kinda.
And WTF, just because you can make a spinning cube in 4 lines, doesn't mean it's that good, what about making a language which can make spinning cubes like this:
"CREATE CUBE -> SPIN"
So, if i create a language which could do that it would be the best language in the world?

HAHAAAA NICE!!! pwned reid

[-Lex]

msgbox (0, "Hello", "World")

Autoit ftw

[EcHoEs]

Then again who would want app to say "Hello world"

[ReidE96]

EcHoEs makes a good point.

And MaiN, if that was all your language could do I'd be worried.

insanesk - No, you can be really specific with it. You just use some other commands.

[Apoc]

You're all missing the point of what C++ and this program is about.

"Hello World" is the traditional first program you do in any language.

DarkBasic is more of an easy way to do not so complex VISUAL programming.

C++ is a language where there are no limits as to what you can do. Literally.

The fact that C++ allows you to manually control the memory your application uses is already a main point why this language has a small heads up over some other languages. Not to mention 90% of the games you play are not made in DarkBasic, but a combination of C++ and C. (Yes sometimes you need some managed code which is easier to do in C than C++)

Now, with my ranting out of the way, please stay on topic. No need to bash a language because it takes 4 lines to write a hello world app.

Ryudop, if you're still using a compiler that requires the 0, you should seriously look into getting a new compiler. The last time I used a compiler that required that was back in 97.

Yeah i know it isn't really needed, but it's a good habit to always include a return statement in non-void functions. (or even in void functions)


*edit*
@post below, void indicates that no value is returned, but you still return to the function that called you.. so just 'return;'.

[Apoc]

Why would you add a return statement in a void function? The sole purpose of a void is to NOT return anything. Most compilers would throw an error about adding a return in a void function...
