How to make your First C++ Program :D

[Master]

Alright heres the CODE and i'll explane how this works.

# include <iostream>

using namespace std;

int main
{
   cout << "Hello World!" << endl;
   return 0;
}

First "#include <iostream>" when you run the program the compiler will look at the cpp header which includes iostream different components make you include different things. Like #include <winsock> etc... Then the "void main(void)" simply makes a function that is kept in the curly braces the function is called main with void parameters Simple Now the cool part. "cout >> "Hello World!" << endl;" This simply puts in some output in the form of "Hello Worl" and endl; put's in a line called: Press any key to continue...

And that is how you make a hello world program I and I hope you understood most of that lol . But I would sudjest getting a book on C++.

this book is what I first used to learn, its not all that hard, and I would greatly recomend this book to everybody . Enjoy!

Hmmm. Dont you need:

using namespace std;

under the <iostream>? Thats what we use.

Yes, you do need to add,

 using namespace std;

, or put

std::cout<<

etc.. and when you run this program you wont be able to see the "Hello World" unless you hold the Execution window open by using

cin.get();

. And dont forget you have to Renurn a value to the main function like 0, to indicate all went well lol..

 # include <iostream>
using namespace std;
int main
{
   cout << "Hello World!" << endl;
   cin.get();
   return 0;
}

That would be the correct code

#include "stdafx.h"

using namespace System;

int main(array<System::String ^> ^args)
{
    Console::WriteLine(L"Hello World");
    return 0;
}

The win32 console version.

if you get board with a language as simple as javascipt I wouldn't sudjest learning C++ being that its so much bigger and complex. Though, if you want to try go ahead.
