Check the two of the following affirmations that are TRUE. You get negative marks if you check those that are false. The main function is a free function, not a member function. Oin the adapter pattern, the Target class must have at least one virtual method. All function template instances share the same static local variables as declared in their function template. All classes inheriting a pure virtual method must provide an implementation for it. Check the two of the following affirmations that are TRUE. You get negative marks if you check those that are false. The value of a pointer is the address of a memory cell. Object slicing happens when reference semantics is used and an object of a subtype is copied into a variable of a base type. Stack unwinding ensures that no memory leaks can result from an exception having been thrown. Dynamically allocated arrays are pointers to statically allocated arrays.
