You don't know what you're talking about. And you apparently are too
stubborn or arrogant to realize that you might be wrong (and in this
case you *are* wrong).

This is a known ambiguity of the standard, where any
A<B<type> > construct will only compile with the two '>' separated,
typically by whitespace. Refrain from giving advice if your own
ignorance is greater than the OP.

Still wrong. Of course I have tried it, many times.
The issue and the fix are well-known, e.g. recently
http://groups.google.c om/groups?selm=brl 37f$sud$1@news. apple.com
http://groups.google.c om/groups?selm=rMY Mb.47226$xy6.11 6719@attbi_s02

By the way, I notice the poster's error message refers to line 135, and
he only posted 5 lines of code, therefore he is lying to us about what
the actual code is that produced the message.

I didn't do any search in Google concerning this problem, but I did
write programs in VC6 and I got an error.
Did you try it in VC or just in google?

It's not an ambiguity. >> is one token, not two.

There are several bugs in VC++ 6.0 that affect programs that use vector and
related classes.

Before you do anything else, be sure that the latest service pack for VC++
6.0 (which I think is Service Pack 4) is installed, as it fixes a number of
those bugs.

One bug that is not fixed, and might be related to your problem, is this:

using std::vector;
vector<int>::si ze_type i;

This code should work, but doesn't work in VC++ 6.0; instead, you have to
say

std::vector<int >::size_type i;

I *think*, but am not certain, that even this latter version of the code
requires Service Pack 4.

I think you're right on this. The code showed by OP could be very possibly
not the source of compile errors. In some other place(s) of OP's code,
std::vector used but <vector> not include'd.

It works just fine with VC6, as does the OP's posted code.

OK post the *exact* code you tried, and the exact text of any error
messages.

What ambiguity?

That's the *only* way to 'separate' them.

'>' and '>>' are two separate tokens.

Yes, I've run into that myself.

<OT info>
Last Service Pack for VC6 is SP5, dowloadable from msdn.microsoft. com,
or can be obtained on CD for a nominal shipping fee.

Missing semicolon on preceding line, who knows? Could be anything.

Poor wording on my part--I was aware that the space was necessary to
make it two tokens instead of one. Thanks for the correction.

Re: Does Vector is not supported by VC++ 6.0??

You have a "space" between std::vector and <int>
std::vector <int>::size_typ e i;

No. Spaces dont matter.

std :: vector <int> :: size_type t;

compiles fine with VC6.

And please dont toppost.
