Remove items from a stl vector

[silverburgh.meryl]

How can I remove items from a stl vector if it exists on another
vector?

In Java, I can do this:
vector v1 = new Vector();
// populate v1

vector v2 = new Vector();
// populate v2

v1.removeAll(v2);

how can I do that in C++?
Do I have to write my own functor and pass that to remove_if()
algorithm?

Which one do you designate 'it'? The item or the vector?

In Java, I can do this:
vector v1 = new Vector();
// populate v1

vector v2 = new Vector();
// populate v2

v1.removeAll(v2);

how can I do that in C++?

Use 'remove_if' and 'find'.

Do I have to write my own functor and pass that to remove_if()
algorithm?

Yes, your own functor would probably be the best (the clearest). Or you
can sort both vectors (or their copies) and then use 'set_difference'.
