Hello World Problem

[ApoC]

Hello, I'm learning via the book Accelerated C.
there's an example that says that I need to write the following code:

#include <iostream>

int main()
{
std::cout <<"Hello World!" << std::endl;
return 0;
}


for some reason, it just won't work (compiling results in "1 failed")

So two questions:
1. What am I(or more accuratly, the book) doing wrong?
2. Anybody knows a better book?:)

Thank you!

What compiler are you using? What exactly was the error message it gave you? It looks fine to me. Compiles and runs fine using Code::Blocks. So sounds like your compiler is at issue.

Thank you for the quick reply.

I'm using Microsoft Visual C++ 2010 Express, and there's actually no error (Or i don't know where to check) :S
here's the output I got though:

Try to reinstall, works for me on Code::Blocks

@ApoC

Did you create your file as a 'Console Application', or a "window's" program? The source code you show is for the console.

[Chervil]

Did you name the file "Lawl.c"? Many compilers will switch between C and C++ depending on the extension of the file name. ".c" indicates C, ".cpp" indicates C++
so you should make sure the file was saved as "something.cpp" .

[ApoC]

Thank you guys again for the quick posts, I appriciate it alot.

Chervil, keen eye there, it worked, thank you very much sir:)

[ApoC]

I have another problem -> I didn't want to post another topic to not make any more spam, but if it's against the rules so please tell me and I won't do it again:

After I'm debugging the debugger won't show me what was printed, it just shows up a window and goes out right away, what should I do?

EDIT:
Managed to fix it:), sorry for the double post.

[JLBorges]

> it just shows up a window and goes out right away, what should I do?

Make the program wait for the user to press enter.

#include <iostream>

int main()
{
    std::cout <<"Hello World!" << /* std::endl; */ << '\n' ;
    std::cin.get() ; // wait till user presses <ENTER>
}
