Hello every one
Today I’m going to write good c c++ tutorials
The tutorials are mine showing my experience in c c++
i my be using some examples rote in some books (if i do i will pot a link or name of the book)
And all the tutorials are at the main topic
I don’t know how my topic count in this case because all I’m going to do is updates the same topic
Any way lets just tray and see
First sings first in order to compile your code you need compiler
That compiler is an application that converts your code from human readable code to
Binary cod or machine code
There is allot of compilers out their
(I will post some links soon)
The first code you might wan do is simple
And do some actual work
Let’s start with the oldest and greatest and simplest code
Hello world

You can get that code from almost any compiler as a simple project


Now what is that code
Let’s explain
Line after line

1-#include <stdio.h>
You tell see that you want to use the input output library
In English you can use the keyboard to input and the
Screen to output
That’s all
2-int main(int argc, char* argv[])
This is the main function
You cant compile your code without this function
I will explain it later
3-printf ("Hello World!\n");


[To be continuing ……]

Actually, #include tells that you want to include a header file that contains code.
#include "hi.h" would mean that you want to include hi.h from the directory that the file containing that code is in.
int argc, char* argv[] isn't really required as parameters for int main() unless you want arguments to be passed from the command line

And overall, printf is mainly a C function. C++ has a better way of outputting.

thanks for reblay i will edit the post
and i know that c++ use "cout" for outpot
and i useed the argc, char* argv[] because i will write som examples about them later
i meant the full line
#include <stdio.h>
not just #include
that tels the compiler that i need to use the input output function in c
that means the code for this functions is in the file "stdio.h"
once moor thanks and fell free to fix any error
in my topic

#include<stdio.h> means to include a header file named standard input/output, whose function is explained by Zamaliphe above.
And main function is the first function from where execution starts.

Zamaliphe, a suggestion to you. You should give/explain whole thing (all functions used by you) at one post itself, no problem the length of the posts increases. Because it gives beginners to learn and people like us to comment on it. In this program, if your motto was only to teach printf function, then there was no need to use the arguments. Also if where planning to show something else with those (as you have said) then you should explain it in one post itself.

Hi im a pc programmer and a game programmer i use Dev - c++ your tutorials arent bad but can you please state what application you are using??

Thanks

Painbringer

OK in windows i use Dev - c++ also
some times i use Microsoft Visual C++ 6.0 and MSDN library
and on Linux i like the old fashion compiler
gcc
on the command line
most of times i create and script to automate the compiling process
using make or even just bash script
and i like c on Linux moor than windows




thanks for your suggestion I'm working on it

by the way I'm too lazy
so it might take few dye's to complete that tutorials

and this is not teach print function only

this is just start

and every one start learning programming

like to see what he dos on the screen

so teach printf function

is the most important sing for beginners

thanks for the comment and i have not start even yet

Hello, i'm a new user in programming and i'm more interested in web interaction ones.
My question is: is c/c++ a good program for web interaction? Is there an easier way to create a gui?
What i want to do is a mysql interaction, consult and confirmation, and include that on vb. is it possible?

wouldn't a "cout" be easier?
with visual C++ 6.0

iostream = input output stream
endl = endline

@zamaliphe: I believe there *still* is a tutorial section of this site, why not just post this stuff there?
Not everyone here is a n00b or needs to see yet another tutorial, and there's a clearly defined
forum feature for it.

About your code - you gave a PURE C program - for crying out loud, you gave arguments to main(),
so what's with the the association with C++?

@Csshih: That's technically bad code is why. You didn't declare a namespace for cout.
It's a lot easier to write printf() than std::cout any day just because you don't have to
stand there all day shifting to get a colon.

Logically speaking, it'd still be easier to d
