Question

Is it permissible for a local variable in one function to have the same name as a local variable in a different function?

Short answer

Answer: Yes, it is permissible for local variables in different functions to have the same name as they have a limited scope and are only accessible within their respective functions, thus not causing any conflicts.

Step-by-step solution

Understand Local Variables

Local variables are variables that are declared within a function or a block of code. They have a limited scope and can only be accessed and manipulated within the function in which they are declared.

Learn About Variable Scope

A variable's scope is the part of the code where it is accessible and can be used. Local variables have a limited scope and are only valid within the function or block in which they are defined. This means that they do not exist or are not accessible outside that particular function.

Analyze Function Interaction with Local Variables

Since local variables are confined within their respective functions, function A cannot interact with or affect the local variables declared and used in function B, and vice versa. This means that they can exist independently and without any conflicts, even if they share the same name.

Determine Permissibility

Given the limited scope of local variables and their independence across functions, it is indeed permissible for local variables in different functions to have the same name, without causing any issues or conflicts in the overall program execution.
