function call without creating object

in C++ you can call function / methods without creating an object of
that Class?

like the the following, it calls Update() + Draw() functions by Class
name CInterfaceGroup + CContainer.

In Java, one can only call method by Class name if it is static
method.

In C++, you can call any function without creating an Object like -
CContainer * cc = new CContainer;
cc->Draw();

=========================

CGraphicsGroup::~CGraphicsGroup() {
}

void CGraphicsGroup::Create() {

}

void CGraphicsGroup::Update() {
	CInterfaceGroup::Update();
}

void CGraphicsGroup::Draw() {
	CContainer::Draw();
}
