Interrupt handlers as member functions _are_ possible. But they must be static member functions. Static member functions don't make use of the implicit 'this' pointer required by normal member functions. The caller of the interrupt handler doesn't know anything about objects and 'this' pointers, so it can't pass a value of such a pointer.

Describe exception handling concept with an example?

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
