Question

You are reviewing the code written by another programmer, and encounter a variable whose name is entirely in capital letters. What might you discern from this variable name?
A. The variable is a symbolic constant.
B. The variable is a reference variable.
C. The variable is part of a program loop.
D. The variable is used to store a dynamic value that is constantly changing.

Answer 1

Answer:

Option A is the right answer.

Explanation:

In any programming language, when a user needs to define the constant variable then he should need to define the variable in capital letter. It is not necessary for the compiler point of view but it is necessary for the standardization point of view. It means that when a user does not define the constant variable in the capital letter then it will never give an error.

Option "a" also states that the variable is constant and the scenario is to define the variable in capital letter hence option a is correct while the other is not because--

• Option b states that the user-defined reference variable but the reference variable is defined with the help of (*) symbol.
• Option c states about the loop variable but the loop variable also can define by small letters.
• Option d states that it is used for dynamic value but for dynamic variable a user can define small letters.
