Explanation / Answer

Answer:

46. Option c (min)

In class diagram, the class has three parts i) class name ii) attributes (data members) iii) operations (member functions)

The second part has attributes or members of the class. So, 'min' is one of the data members of the class Clock.

47. Option b (setTime(int,int,int))

Any method which doesn't return anything is 'void' type.

In the given options, setTime(int,int,int):void means setTime(int,int,int) returns nothing.

48. option a (public Clock() { setTime(0,0,0);}

49. Option c (class)

Constructors have same name as the class

50. Option c (the operator new)

new operator is used to allocate the memory for instance variables of objects of a class.
