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

[Ram Laxman]

I have used vector in the VC++ compiler. I have included

#include <string>
#include <algorithm>
#include <vector>

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


test.cpp(135) : error C2653: 'std' : is not a class or namespace name
error C2143: syntax error : missing ';' before '<'
error C2501: 'vector' : missing storage-class or type specifiers
error C2143: syntax error : missing ';' before '<'
error C2653: 'std' : is not a class or namespace name


Does anybody know what is the problem??

vector is supported by VC++6 and your code looks correct. So either the code
you've posted isn't the code you've compiled, or your compiler is installed
incorrectly (perhaps its looking in the wrong places for header files).

Try it without "std::".

You obviously haven't posted the code that produced the above error so
it will be hard to help you. Have you tried compiling the 6 lines you
have posted by themselves?

That silly "std is not a class or namespace name" error message
reminds me of a situation I had once. I had a missing closing brace
in a header file. Perhaps you're including something that you didn't
show here and this causes the problem? Just an idea.

Remove this ^ space

Are you imposing your coding style on the OP? . The space is perfectly
legal.

The question is whether it is legal with VC or not.
for example this one:
vector<vector<int>> will not work for sure because of
^^
and the only solution is to write
vector<vector<int>/**/>

Best regards, Michael

 

[Michael Mellor]

The question is whether it is legal with VC or not.

If VC++ 6 does not support the space being there it is well broken but
then again it is at least a 6 year old compiler, I wouldn't dream of
using gcc 2.8 which was released about the same time.

for example this one:
vector<vector<int>> will not work for sure because of
^^
and the only solution is to write
vector<vector<int>/**/>

or if vector< vector<int> > doesn't work:

typedef vector<int> int_vector;
vector<int_vector> obj;

Doesn't "vector<vector<int> >" work?

I have used vector in the VC++ compiler. I have included

#include <string>
#include <algorithm>
#include <vector>

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

Those lines compile with no error using MSVC6 here.

For trouble with your compiler, as opposed to the C++ language issues,
see a newsgroup dedicated to your compiler or platform.
This issue is covered in Marshall Cline's C++ FAQ. It is always good to
check the FAQ before posting. You can get the FAQ at:

Bogus. An extra space there is of no significance.

Wrong, no space-filling comment required. Standard solution is
vector<vector<int> >

Naturally, operator>> will not work there.

Just inserting one space doesn't help.
Try it if you don't believe.

 

[Michael Mellor]

Try it if you don't believe.

Firstly, I assume your entire discussion is about VC++ 6.

vector<vector<int> > obj;

is the normal way to solve the problem. I couldn't imagine anyone would
write a compiler in which this does not work. Anyhow, you claim that
VC++ 6 does not support the insertion of a space but a quick google
search suggests it does.

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.

 

[David Harmon]

Still wrong. Of course I have tried it, many times.
The issue and the fix are well-known, e.g. recently
http://groups.google.com/[email protected]
http://groups.google.com/groups?selm=rMYMb.47226$xy6.116719@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?

Post the code.

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