(C) first=[1,2,3,4,5] ,second = [1,2,3,4,5]
(D) first=[1,2 ,3,4,5,6] , second = [1,2,3,4,5,6]
(E) None of these 

61. Which of the following is not a correct way to initialize an array? (A) int n[5]={0, 1, 2, 3, 4, 5}； (B) int n[]={0, 1, 2, 3, 4, 5}； (C) int n[5]={1}； (D) int n[5]={1, 5, 9}； (E) int n[5]={0}；

62. Polymorphism is implemented through: (A) Non-const functions. (B) Member functions. (C) Non-virtual functions. (D) virtual functions and dynamic binding. (E) inline functions.

63. A copy constructor must receive its argument by reference instead of by value because: (A) Otherwise the constructor will only make a copy of a pointer to an object. (B) The copy of the argument passed by value has function scope. (C) The pointer needs to know the address of the original data, not a temporary copy of it. (D) Otherwise infinite recursion occurs. (E) Otherwise the constructor will never be called.

68. Call-by-reference can achieve the security of call-by-value when: (A) A large argument is passed in order to improve performance. (B) A pointer to the argument is used. (C) The const qualifier is used. (D) The value being passed is small. (E) The argument is an array.

69. student is a base class and TA is a derived class, with a redefined non-virtual coding function. Given the following statements, will the output of the two coding function calls be identical?   (A) It depends on the implementation of the coding function. (B) It depends on the value of object t. (C) Yes. (D) Yes, if coding is a static function. (E) No.
