1. consider the following declarations: classxclass { public: voidfunc(); void print() const; xclass(); xclass(int, double); private: int u; double w; }; and assume that the following statement is in a user program: xclass x; a. how many members does class xclass have? b. how many private members does xclass have? c. how many constructors does class xclass have? d. write the definition of the member function func so that u is set to 10 and w is set to 15.3. e. write the definition of the member function print that prints the contents of u and w. f. write the definition of the default constructor of the class xclass so that the private member variables are initialized to 0. g. write a c++ statement
