I'd like to have a vector in which at runtime objects which are instances of two subclasses of a common class should be inserted, as follows:
1 2 3 4 5 6 7 8 9 10 11
class A {...}
class A1 : A {...}
class A2 : A {...}
vector<A> myVector;
A1 a1 = new A1();
A2 a2 = new A2();
A a = new A();
myVector.push_back(a1);
myVector.push_back(a2);
myVector.push_back(a);
Is this possible in C++? If yes, how to do it? The way I sketched it above doesn't seem to work, it always complains about a1/a2 not being of type A.
