Welcome developer! In this document, we'll discuss how local variables can perform different functions when given the same name. We'll look at an example of a common issue, how to fix it and an FAQ section that might help you further. Let's dive in!
What is a Local Variable?
A local variable is a named identifier used by programs or functions to reference an item or data stored in the memory or stack. It is a temporary storage space and can only be accessed by the program that created the variable.
Common Issue
When local variables are given the same name, it can lead to confusion since both have the same name and work on the same data. This can result in issues such as unexpected changes, overwriting existing data, and errors that can be difficult to debug.
How to Fix the Issue
To fix this issue, it is important to ensure that each local variable has a unique name. This allows for easier debugging, better understanding of code, and improved readability. Some programming languages have built-in checks for ensuring that local variables have different names.
