Hi everyone,
Here about what it is.
vector<vector<P oint3D> > pVector0;
pVector0 is a vector of vector of 3D points.
pVector0[i] is a vector of 3D points.
pVector0[i][j] is a 3D point.
I wanted to add a point pt3D to the m vector in pVector0, I have
write these two instructions which belong to a C++ program.
vector< vector<Vector3D > > pVector0;
pVector0[m].push_back(pt3D );
I have as error message: Segmentation fault (core dumped)
Could anyone give me suggestions?
Thanks!

What's the size of 'pVector0'? You're trying to access the m-th
element of it, do you know if it even exists?

The size of pVector0 is not known.
I wanted to add m empty vectors to the vector and to add the point pt3D
to m vector.
vector< vector<Vector3D > > pVector0;
pVector0.insert (pVector0.end() ,m);
pVector0[m].push_back(pt3D ); ha************@ yahoo.fr wrote: Victor Bazarov wrote:

REALLY? Have you tried calling pVector0.size() ?

If you add m vectors to the vector, what's their indices? vector< vector<Vector3D > > pVector0; pVector0.insert (pVector0.end() ,m); pVector0[m].push_back(pt3D );

Are you sure this 'm' vector exists?

If that's the only 2 lines you wrote, there's a problem. The vector is
empty and you are trying to access it's mth element. Illegal.
If you want to add a point, you first need to add a vector of points.
std::vector<Vec tor3D> vector_of_point s;
vector_of_point s.push_back(a_p oint);
pVector0.push_b ack(vector_of_p oints);
Remember: pVector0 is a vector of vectors of points.

I have tried calling pVector0.size() ,
pList0.size() = 0 I wanted to add m empty vectors to the vector and to add the point pt3D to m vector.
If you add m vectors to the vector, what's their indices?
I added m vectors at the end of the vector. vector< vector<Vector3D > > pVector0; pVector0.insert (pVector0.end() ,m); pVector0[m].push_back(pt3D );

It looks like there's a pretty serious CSS bug in IE6
(v6.0.2800.1106). The HTML below is validated STRICT HTML 4.01 and

For some reason, there's an annoying vertical gap between adjacent
rules that doesn't go away. This looks like IE6 is incorrectly
setting the margin to some arbitrary value.
Does anyone know if this is a known bug at MS? If you know of one,

Hi,
I am currently writing a simple PHP program that uses an XML file to
output rows for a 'Whats New' page. Once written, I will only require
updating the XML file and any pages that use the XML file will get
their row content from there. The rows may look some thing similar to
this:
- Added <a>mailing list</a> functionality to <a>homepage</a>
- Competition winners announced, click <a>here</a>

My problem is that .NET will not allow me to insert escaped '>'

seems to strip out only those type of characters, because other escape
codes DO work (eg. "e;)
