how to output the wchar_t type string

[abbu]

int main()
{
wchar_t p[]="Good Morning";
}

How to use cout on p.
That is, can I use cout<<p;

It's not working.

Can anybody suggest how to use cout on wchar_t type strings?

Thanks

Mostly when it comes to wide strings you just use the normal funcs but add
"w" to the start.
eg.:

const char *str = "text";
printf(str);

const wchar_t *str = "text";
wprintf(str);

cout outputs a standard byte stream (ansi)
wcout outputs a wide stream (e.g. unicode)

The following program works fine here:


#include <iostream>

int main()
{
wchar_t p[] = L"Good Morning";
std::wcout << p << '\n';
}

After posting this i noticed that i made bad usage of printf and wprintf.

In case some people new to programming sees this, i better point out that
this is bad:

char *str = "text";
printf(str);

If str has "%s" inside it will crash the app.

Correct usage:

char *str = "text";
printf("%s", str);

g++ 3.4.4 on Windows does not support wide character streams.

Also be aware that what the wide characters streams do, is to convert to
narrow characters, in some /unspecified/ way.

I guess I should have mentioned that this was using VC++ 7.1 (VS .NET
2003) on Windows XP.

Thanks for the info regarding wide streams. I never use them but this
example seemed easy enough to whip together.

You need an L ahead of the text literal to make it wide.
