Answer ALL the questions                                                                                      (8 x 5 = 40 marks)

 

1. (a) Distinguish between Class and Structure.

(or)

(b) Analyse the following code with respect to syntax and semantics:

Class C

{

intx; const int y; public: C(int a, int b)

{x=a; y=b}

};

function=() by defining a string class with these functions.

(or)

in C++? Give an example.

example.

members, which access specifier must be used?

(or)
