Question
Give a definition for a class SmartBut that is a derived class of the base
class Smart, which we reproduce for you here. Do not bother with
#include directives or namespace details.
class Smart
{
public:
Smart( );
void print_answer( ) const;
protected:
int a;
int b;
};
This class should have an additional data field, crazy, that is of type bool,
one additional member function that takes no arguments and returns a
value of type bool, and suitable constructors. The new function is named
is_crazy. You do not need to give any implementations, just the class
Answer
{
public:
SmartBut( );
SmartBut(int new_a, int new_b, bool new_crazy);
bool is_crazy( ) const;
private:
bool crazy;
};
