TL;DR

Learn about local parameters in functions, how they behave, and their properties.

Key Insights

• 🧭 Local parameters are variables declared within the brackets of a function and receive values passed to the function.
• 🧭 Changes made to local parameters do not affect the original values passed to the function.
• ❓ When a function is terminated, all resources associated with the function, including local parameters, are deleted.

Questions & Answers

Q: What is a local parameter in a function?

A local parameter is a variable declared within the brackets of a function. It receives the value passed to the function and is stored in a new variable.

Q: Can changes made to a local parameter affect the original value passed to the function?

No, changes made to a local parameter do not affect the original value passed to the function. The local parameter is a separate variable that holds a copy of the value.

Q: What happens when a function is terminated?

When a function is terminated, all resources associated with the function, including local parameters, are deleted. Any changes made to the local parameters are lost.

Q: Can local parameters have the same name as variables in the main function?

Yes, local parameters can have the same name as variables in the main function. The local parameter will only receive the value passed to the function and any changes made to it will not affect the original variable in the main function.

Summary & Key Takeaways

• Local parameters, also known as parameters or arguments, are declared within the brackets of a function.

• When a value is passed to a function, it is received by a local parameter and copied into a new variable.

• Changes made to the local parameter do not affect the original value passed to the function.
