Virtual function or template for c++ polymorphism. What is better and more convenient?

Answer 1

They serve different purposes. Templates can only be used for static polymorphism: when the types of the operands are known at compile time. If you need to change the behavior at runtime (if you use pointers / references to the base class), then virtual functions are indispensable.
