std::string with non-type template arg

[Default User]

I received some code from another programmer who happens to be out of
town. In this, he had something like:

struct st
{
std::string s<20>;
};

Looks like it's setting the string size.

VC++ 6 produced an error in compilation, complaining of a syntax error
before the <20> part. I looked at Stroustrup and Josuttis to see if I
could find something about a non-type template argument for doing this,
and didn't really see anything, although I may have just not realized I
was seeing it. I didn't see any examples similar to this either.

Normally when I want to specify string size at declaration, I use the
constructor:

std::string s(20, 0);


Presumably this guy had compiled it on whatever platform he uses
without problem, although I can't check with him. Is this an error on
his part, or yet another VC++ template problem?

The code presented isn't C++. As to VC++, ask in
microsoft.public.vc.language.

That's all I needed to know.

As it seems to be correctly diagnosing a syntax error, that doesn't
seem needful.
