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.
