Chapter 8, Problem 1MC

Program Description Answer

In an array, size declarator is used to specify the number of elements in an array.

Hence, the correct answer is option “B”.

Explanation of Solution

Array size declarator:

• The number that is given inside the square brackets at the time of array declaration is called as array size declarator.
• The value should not be in negative.
• In order to avoid changing of size inside the source code, the programmers desires to use named constants as array size declarator.

Example for array size declarator:

int arrayName[10];

In the above example:

int – It is the data type

arrayName – Name of the array

10 – Size of the array

Explanation for incorrect options:

Subscript:

Each and every element in an array is assigned to a special value called as subscripts or indexes.

Hence, the option “A” is wrong.

Array Name:

Array name is not used to specify the number of elements in an array rather it mentions the name of the array.

Hence, the option “C” is wrong.

Initialization value:

It is nothing but the data that are given inside the array.

Hence, the option “D” is wrong.
