Quark,

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

Quark,

Quark,

class Foo { public: Foo(int i) { } }; class Bar : virtual Foo { public: Bar() { } }; Bar b; Referring to the above code, when the object 'b' is defined, a compiler error will occur. What action fixes the compiler error? a) Adding a virtual destructor to the class Bar b) Adding a constructor to Bar which takes an int parameter c) Adding "Foo()" to the Bar constructor d) Adding a copy constructor to the class Foo e) Adding "Foo(0)" to the Bar::Bar initializer list

Quark,

Which one of the following describes characteristics of "protected" inheritance? a) The base class has access only to the public or protected members of the derived class. b) The derived class has non-public, inheritable, access to all but the private members of the base class. c) The derived class has access to all members of the base class. d) The private members of the base class are visible within the derived class. e) Public members of the derived class are privately accessible from the base class.

Quark,

The "virtual" specifier in a member function enables which one of the following? a) Monmorphism b) Late binding c) Metamorphism d) Solomorphism e) Inheritance

Quark,

class X { public: int x; static void f(int z); }; void X::f(int y) {x=y;} What is the error in the sample code above? a) The class X does not have any protected members. b) The static member function f() accesses the non-static z. c) The static member function f() accesses the non-static x. d) The member function f() must return a value. e) The class X does not have any private members.

Quark,

template class Obj { T my_t; X my_x; public: Obj(T t, X x) : my_t(t), my_x(x) { } }; Referring to the sample code above, which one of the following is a valid conversion operator for the type T? a) T operator T () { return my_t; } b) T operator(T) const { return my_t; } c) operator(T) { return my_t; } d) T operator T (const Obj &obj) { return obj.my_t; } e) operator T () const { return my_t; }

Quark,

int f() { int I = 12; int &r = I; r += r / 4; int *p = &r; *p += r; return I; } Referring to the sample code above, what is the return value of the function "f()"? a) 12 b) 15 c) 24 d) 17 e) 30
