wchar_t

[Gaijinco]

I'm from Colombia a country where we speak spanish. I had always used
char's and the standard functions for I/O and other matters that had to
deal with characters.

However today I tried to use some things with wchar_t with poor
results.

The first problem is that there is almost none documentation. I checked
books from Deitel & Deitel, O'Reilly, Sam, Addison Wesley but none had
anything about wchar_t. I tried google but then again there was nothing
really useful and the information I found was a little inacurate as I
tried to compile programs with it.

Does someone knows of a good source of information? Does have anyone
used wchar_t and survived?

Thanks a lot.

Exactly what did you try to do with type 'wchar_t'?
What results did you expect, what results did you
get, and what was the difference?

For starters I'm trying to print "Ahí está el problema"

It was supposed to be along the lines of:

#include <wchar.h>
#include <iostream>
using namespace std;

int main()
{
wcout << L"Ahí está el problema";
return 0;
}

But the compiler says it doesn't find "wcout".

First note that the 'wide character' type (wchar_t)
is not specified by C++ to include all of the
characters in your string literal above. Your
operating system and/or implementation must provide
that.

It was supposed to be along the lines of:

#include <wchar.h>

You don't need this header in C++, where 'wchar_t' is
a keyword (i.e. it's a built-in type).

#include <iostream>

This header declares the standard built-in stream objects,
including the 'wide stream' objects such as 'std::wcout'.

using namespace std;

int main()
{
wcout << L"Ahí está el problema";
return 0;
}

But the compiler says it doesn't find "wcout".

Therefore your compiler does not conform to the
C++ standard. Try a different compiler (or perhaps
a more current version of the one you're using).
