QUESTION 2

Which statement is correct?

		Pointer variables are just memory addresses and can be assigned to one another without regard to type. For example: double *dPtr; int *iPtr; ... iPtr = dPtr;
		One can use the & operator to extract the value that a pointer points to. Ex: int *iPtr; ... cout << &iPtr;
		The declaration below declares three pointer variables of type pointer to double that is, a pointer of type (double*) double* p1, p2, p3;
		You can get a pointer value to initialize a pointer variable from an object of an appropriate type with the address-of operator, &. For example: int *iPtr, iVal; iPtr = &iVal;

QUESTION 3

Which statement is correct?

		A constructor is like a function. It can return any type value needed.
		A constructor is a special kind of member function. It is automatically called when an object of that class is declared.
		You can write a class that is useful with all its constructors in the private section.
		A constructor is always named construct with class name attached. If the class is Foo, then the constructor name is constructFoo.

QUESTION 4

Which is incorrect?

		When declaring several pointer variables, there must be one pointer declarator * for each pointer variable.
		You can get a pointer value to initialize a pointer variable from an object of an appropriate type with the address-of operator, &.
		Pointer variables are just memory addresses and can be assigned to one another without regard to type
		A pointer is a variable that holds the address of some other location in memory.

QUESTION 6

Which is incorrect?

		There should eventually be a call to the operator delete on a pointer that points to the memory allocated by each call to new.
		A function can return an array.
		Dangling pointers present a problem in C++
		Dynamic variables or dynamically allocated variables in C++ are created and destroyed according to the programs needs.

QUESTION 11

Function members of a class gain access to the calling object's members by

		a pointer to the calling object that is implicitly provided by the compiler. The name if this pointer is this. The members are prefixed implicitly by this-> as in this->membername
		there is no particular mechanism, the variables just know what the calling object is and automatically refer to the calling object
		a variable called self that is an alias for the calling object. This self is used to access the members of the object as in self.membername
		None of the above
