Answer / jaya

in c data hiding is not possible and we have to write
complete program at a time.whereas in c++ data hiding is
possible and one can divide a huge program into certain
small programs later combine it into one as per one's
choice.moreover we hav header file different.eg:<stdio.h>
in c supports printf & scanf statements while <iostearm.h>
in c++ supports cout statements......

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
