Study Notes

Function Purpose

Functions are designed to perform specific tasks within a program.
They organize code, making it easier to read, maintain, and reuse.

Functions with No Return Value

Functions without a return value are often used to perform actions that modify the program's state, such as updating variables or printing output.

Benefits of Using Functions

Functions promote code reusability, allowing you to call the same code block repeatedly without rewriting it.
They improve code organization and readability, breaking down complex tasks into smaller, manageable units.

Function Parameters

Function parameters are variables that act as inputs to a function, providing data that the function operates on during execution.

Scope of Variables Inside a Function

Variables declared inside a function are considered local variables and their scope is limited to the function's execution block.
This means that variables within a function are inaccessible from outside the function's scope.
