If std::vector <TMyClass> MyVector; --> How to remove MyVector[i] ?

[Guest]

Say we have a vector defined as

std::vector <TMyClass> MyVector;

and we appended N number of element (N>1) to our vector (ie. MyVector.size()
is N)

How can we remove/delete an individual element MyVector (where 0<i<N) in
such a way that after the remove/delete operation MyVector.size() will be
N-1 ?

Use vector::erase() member function. Make the iterator that points
to the i-th element by applying + to the result of a call to 'begin()'.
