Hey,
Sooo
Their was an "awesome" book posted in the ebooks section called
C++ Primer Plus 5h edition by Stephen Prata
I figured that i might as well give C++ a go!
Downloaded Microsoft Visual Studio (Ultimate) ; )
Copied Pasted the first source code into the compiler
Tried to build it
FAIL
// myfirst.cpp--displays a message
#include <iostream> // a PREPROCESSOR directive
int main() // function header
{ // start of function body
using namespace std; // make definitions visible
cout << “Come up and C++ me some time.”; // message
cout << endl; // start a new line
cout << “You won’t regret it!” << endl; // more output
return 0; // terminate main()
} // end of function bodyWhat did i do wrong, how should this look?
I
Is this book outdated, will i run into a lot of problems because its too old?
(Was published in 2005)
If so should i switch over to another book (Which one???)

Welcome to evilzone btw.
Tough i will prefer not using visual studio related to c++ (my opinion, do what you like).
Maybe try some other programs like dev-c++, where its more about the coding than a user friendly-stunning graphics- and a form designer.
As well in the beginning you will have allot more pro's with just a clean and tiny app.

Okay
Im too lazy to download another Environemnt thingy
(Visual Studio was 2 gigs and im almost over my bandwith limit :( )
But i tried making a simpler app.
#include "stdafx.h"
#include <iostream>
int main()
//int _tmain(int argc, _TCHAR* argv[])
{
cout << "hello";
return 0;
}
Now i only have one error
Error: Identifier "cout" is undefined
???wtf???
EDIT
(Btw TY, i was on before the new look came, ;) )

your missing namespace standard. To implement it, add a line immediately under your #includes with the text "using namespace std;" This will allow you to use many of the common expressions like cout and cin.
using namespace std;
your code is also overly explicit, you could accomplish the same thing with
#include <iostream> // this calls for the input output stream
using namespace std;
int main(){
cout << "Hello world, please kill me before my programmer makes me his slave!"
return 0;
}
you don't need any args in int main() in almost every case, no need to fuck with it.

Alright, so when i run it your way i get these errors

========== Rebuild All: 0 succeeded, 1 failed, 0 skipped ==========
the code im running for that is
#include <iostream>
using namespace std;
int main()
{
cout << "hello";
return 0;
}
whats wrong?

Here's your basic C++ Hello World:
#include <iostream>
using namespace std;
int main ()
{
cout << "Hello World" << endl;
return 0;
}
It'll work just fine in VS Ultimate.
Important note: If you copy / paste example for C++ Primer Plus some chars are not good. Like the " (good) are ” (not good).
I attached a file containing all the example from the book with proper char, syntax, indent, etc.
And I also attached answers to some of the problems (There are problems at the end of each chapter). It'll help you a lot.

TYVM
Downlaoding attahcments now :D

Sorry for the double post
But
i tried your code
nothign will work unless i have
#include "stdafx.h"
at the top of the code
-
Ah perhaps you didn't create the project properly.
New Project -> Win32 Console Application -> Check "Empty Project" -> Finish
-
Satan911 beat me to it. Once you've got a project setup properly, right click the "source files" folder on the right and hit add then new item, be sure to select c++ file, just so we're working on the same config in VS10. Damned VS10 does some hacky shit, so definitely important.
-
This is why its better to use something like codeblocks (Or Xcode in my case) :P. Although I do use VS Ultimate occasionally, personally, it can be a little odd in how it handles and does things considering I have a unix background.

I used to hate Visual Studio when I started C++ and switched to Codeblocks (that's still what I use on linux). But for school project we need to use VS and I learned to love it. It's really powerful and has some nice features Codeblock doesn't (Mainly CTRL + Space for auto-complete and some other stuff). I'm not a fan of Microsoft but I'm starting to see why VS is widely used.

Well I use Xcode 4 which can now compete with those features to a certain extent. Personally, since I'm on a mac, I use Xcode although I hate apple making you pay for xcode 4 but thats why there is bittorrent.
-
Yea Xcode looks great. I haven't really used it but I'm working on a project with someone else and he's coding on Xcode and sometime I use his computer and it looks really complete.

Xcode 4 is. 3 didn't have good autocompletion or anything but Xcode 4 finally does and is really nice. Although, there are some annoying features but there are some which not even VS has, local git repository for each project for example and it automatically manages them and updates them. And even has support for remote repositories. But an annoying features is defaulting to llvm compiler 2.0 which has weird error generation. However, a nice feature is the static analyzer. So there are some ups and downs. It is also easy to use once you read the first few pages of documentation (to quote arstechnica, RTFM (Read The Fucking Manual) ).

Advice for fresh starter...learn C first.
Next little bit..get a decent IDE that's not going to cripple you and your code: Code::Blocks (http://www.codeblocks.org/)
