Question

These are declared variables that are never used in the source code.
Select one:
a. Anonymous Variables
b. None of the choices
c. Explicit Variables
d. Implicit Variables

Answer 1

Explict variables are never used in the source cods

Answer 2

In computer programming, an Anonymous Variable is a variable that is declared but never used in the source code. These variables may be declared by mistake or as part of a larger code block that is no longer needed. They are also called "dead" or "unused" variables.

• Since these variables are never used, they do not serve any purpose in the program and can be safely removed without affecting the program's functionality. However, they can take up memory space and may slow down the program's execution.

• It is considered good programming practice to remove or comment out any anonymous variables in your code to keep it clean and efficient.

• c. Explicit Variables - this option suggests that the variables in question are explicitly declared, meaning they are declared with a specific data type and assigned a value or memory space. However, the term "explicit variable" does not necessarily mean that the variable is used in the code. A variable can be explicitly declared but never used, making it an anonymous variable.

• d. Implicit Variables - this option suggests that the variables in question are implicitly declared, meaning they are not explicitly declared with a data type and memory space, but instead are created and assigned a value based on the context of the program. However, the term "implicit variable" does not necessarily mean that the variable is used in the code. A variable can be implicitly created but never used, making it an anonymous variable.
