Explanation / Answer

answers

13. d) all the above

explanation : syntax --> int arrayname [] new int[size]; here declaring a arrary of type int and also specifying its size

14. A) private access specifier is used on class fields

explanation: by making data members private its not accessable by outer class in tern protecting te data

15. D) has the same as class

explanation: a constructor by definition is used to construct object, no return type, not even void.

16) compilation error

explanation: as the array elements type is int ..but it is initialiased with hexadecimal NOTE: array elements are always homogenious type

17) value of x[8] is 180

explanation : y =100 , initially x[0] = 100 ..for each loop execution y is icremented by 10, therefore x[1]=110, x[2]= 120......... x[8] = 180
