[C++]Hello World; Your first C++ Program
[C++]Hello World; Your first C++ Program
Hello guys, thought I'd start off with a nice simple tutorial on making your first C++ Program. I'm only 14 so your probably better off to go Google a more detailed tutorial 
.
I'm assuming you have a compiler at this time, if you don't then go and torrent Microsoft Visual Studio. Personally i use 2003 .Net because it best fits my needs, but any is good really.
After you have a compiler open up a new Win32 Console Application and name it whatever you want.
If you're using MSVS, when you start a new project in the settings select 'Empty Project' to stop any precompiled headers.
Please Read: DON'T Just copy and paste! You WONT learn anything unless you retype it out later, type it out yourself. You will learn a hell of a lot more then just copy and pasting.
Don't worry about this too much for now, but iostream and std contains some basic functions that we're going to be using.
Next Add~
int main() is the what our program will execute(use) when you run it.
int stands for integer which means that we're going to have to return a value in main() else we will get compile errors!
"{" and "}" are the opening and closing brackets for "main()", { is where main() starts and } is where main() ends.
These aren't just for main() though! You can use these for any of your own voids/integers/methods that you create, for instance
"void myVoid() { }"
Here the brackets do exactly the same thing, anyway, moving on~
Add the rest of the code into your main() integer.
{ Remember to add the code in between the brackets }
cout stands for "console output" and is used to output data onto a console (The black box looking thing).
Anything after the operator "cout <<" is outputted onto the console, because we're outputting a string we will use speech marks.
The full code "cout << "Hello World!" << endl;"
outputs 'Hello World!' and endl means end line so it goes to the next line.
cin.get() basically 'pauses' the programming until you press a key, stopping our program from just flashing open and close;
"return 0;" Remember what i said earlier about main() being an integer and needs to return a value, well this just returns the value 0.
Now the code should look like this:
Notes
We use ";" to declare the end of a line, you can also however use it to seperate different things and put your code on one line like this:
I don't want to go into too much detail about cin, it stands for "console input", try googling it 
.
Ending Program
Now we are finished, this is what our program should do on a console screen:

sheeewwwwweeeeeeettttt
Thanx mate, i need downloadl ink, plz get it for me. of u can, thanx!!!
Hey thanks for the tut it worked for me> i am using relo2 to compile , build and run with a borland c++ add-on compiler. really appreciate ur good tut and look foward to seeing more. Thanks!!!!!!!!!!
