Xcode

Mods's I'm not sure exactly where something like this would go but this was the best I could do

**********************************

I use Xcode for writing numerical code in C++ but when I try to compile the same code in Windows XP, (Bloodshed), Salford C++ compiler and Visual C++ I keep getting errors. The Salford compiler compiles the code but gives me execution errors. Visual C++ and Bloodshed gives me weird errors ( i.e. Visual C++ thought "cout << " was a undeclared function) when compiling. What I'm thinking is casuing the problem is the way I'm starting out my source code.

***************

# include

using namespace std;

****************

So does anyone have any others idea's and does anyone have a solution to my dilemma. Pretty much I would like to use both macs and pc's to compile the same code

#268017

I always rember doing "#include "

#268028

I always rember doing "#include "

that's the C way on doing it, not the C++ way

could you show me the exact error you get in Visual C++ ?

#268038

You shure, i never learned C :/

that's the C way on doing it, not the C++ way
could you show me the exact error you get in Visual C++ ?

#268041

I think raduking means that its a little old fashioned to include iostream that way but it still works.

@idicula: I'm not sure why you're getting errors - I did some C++ programs on Xcode then used the source on Codewarrior. What is your error message?

#268054

If I remember C++...

#include <iostream>

using namespace std;

...and

#include <iostream.h>

...give you the same results.

#268064

#include is simply wrong. Many compilers still support it tho, because there's quite some code that needs to be compiled from before the standard ('98).

#include <iostream>

using namespace std;

and

#include <iostream.h>

are not equivalent: iostream.h is not a std-header and thus nothing of the code resides in the std-namespace.

#268069

well for salford compiler I got an error saying that my function QBar() was not valid and that my array wasn't right anyway here's my code.
