Functions and Procedures

Procedures and functions are essential concepts in programming that allow developers to break down complex tasks into smaller, manageable pieces of code that can be reused throughout a program.

A procedure is a named section of code that performs a specific task. The procedure does not return a value and typically modifies data within the program. Procedures are used to group related tasks, such as input/output operations or data validation, and can be called from other program parts.

A function is a named section of code that returns a value. It may or may not modify data within the program. Functions are used to perform specific calculations or operations and can be called from other parts of the program.

Both procedures and functions can take arguments; inputs are passed to the code block to perform the task. For example, arguments can be used to provide a code block with necessary data or modify the behavior of the code block.
