Explanation / Answer

Answers:

1. b

Array is for holding elements of same data type. So, every element has the same data type.

2. c

In c++ or java, "new" operator is used to create an object.

3. a

The syntax for declaring array with size N is

<datatype> name_of_array [<size>] ;

So, based on the syntax, the below one is valid

int array[6];

4. d

To access the element of an array, need to specify subscript (index or expression) of integer type within the square brackets.

subscript can be index or expression (evalutation gives integer value) and the type of subscript should be integer. So all the options are valid answers.

5. c

Array of N elements can indexed from 0 to (N-1). Therefore, array of 10 ten elements can be indexed of 0-9. The highiest array subscript will be 9.
