Do you call on your class's constructor when using the push_back() vector funtion?

example:

myVector.push_back( classConstructor( arg1, arg2, arg3) );

would this be correct?
 
when pasing a parameter is used the copy contructor. So for a right passing of parameter implement
classConstructor( classConstructor&) but when calling the function you can use any constructor, however after this contstructor anyway will be called copy contructor.

thanks!

one last question.

does the vector class come with a function that can delete a particular element.

example:

vector<int> myVector;

myVector.push_back(1);
myVector.push_back(2);
myVector.push_back(3);

how would i delete the 2 (which corresponds to myVector[1])from myVector?

is there a myVector.delete( element# ) included in the vector class?
 
use remove and erase. Remove will move elements from the right side of element to n position in the left, but erase will delete physically elements between iterators you specify. Read STL manual for more information.
