Overriding functions can lead to unintended behavior if not implemented properly. One common issue is that derived class objects may behave unexpectedly when used in a context where they should be treated as base class objects. Additionally, changing the behavior of an inherited function can break existing code that relies on the original functionality.

class Alpha { public: char data[10000]; Alpha(); ~Alpha(); }; class Beta { public: Beta() { n = 0; } void FillData(Alpha a); private: int n; }; How do you make the above sample code more efficient? a) If possible, make the constructor for Beta private to reduce the overhead of public constructors. b) Change the return type in FillData to int to negate the implicit return conversion from "int" to "void". c) Make the destructor for Alpha virtual. d) Make the constructor for Alpha virtual. e) Pass a const reference to Alpha in FillData
