Qt Code:

Switch view

//my vector is: 700 vectors of 11 vectors of double
vector < vector <double> > example;
//fill example.........
vector < vector <double> >* _set = &example;	
 
vector < vector <double> >::iterator iit = _set->begin();
cout << " iit size " <<  iit->size()<< endl;  //print 11; but i need 700......how?
 
for (; iit != _set->end(); ++iit) {
	cout << (*iit)[0] << endl; 
	(_set)->erase( (iit) );//doesn't work

//my vector is: 700 vectors of 11 vectors of double
vector < vector <double> > example;
//fill example.........
vector < vector <double> >* _set = &example;	

vector < vector <double> >::iterator iit = _set->begin();
cout << " iit size " <<  iit->size()<< endl;  //print 11; but i need 700......how?
	
for (; iit != _set->end(); ++iit) {
	cout << (*iit)[0] << endl; 
	(_set)->erase( (iit) );//doesn't work

To copy to clipboard, switch view to plain text mode

I can't use this vector....I need to erase the first element (0) from the head of each 700 vectors. How can I do?
