Hello
I ve this two file:

Conversion.h, conversion.cpp

Code conversion.h:

using namespace std;
class Conversion
{
public:
Conversion();
};

Code Conversion.cpp

#include <iostream.h>
#include "Conversion.h"
using namespace std;

Conversion()
{
cout << "test";
}

with g++ C.* I recive the following error:
Conversion.cpp:4: error: expected unqualified-id before ')' token

I really don't understand where is my mistake.
Any help will be very appreciate :)

Thanks

You have to tell the compiler what class this function belongs to. Change
to
Conversion::Conversion()

Ahem, you haven't included any header that uses anything from namespace std,
so what is this doing there?

If you are learning from a book or any kind of tutorial, you should
definitely dump that book, because it is trying to teach you code in a
dialect that predates the C++ standard, which is almost ten years old. In
other words, the tutorial is for sure not up to date. The standard-conform
equivalent to the above is

#include <iostream>

_ALWAYS_ turn on warnings and always make sure you understand them before
you ignore them. For GCC that is with '-Wall'.
