Functions: Building Blocks of Reusable Code
What is a Function?
- A function is a self-contained block of code designed to perform a specific task.
- It can take inputs (called parameters) and return an output.
- When designing functions, focus on a single responsibility.
- This makes them easier to test and reuse.
Modularization: Structuring Code for Clarity
Definition
Modularization
Modularization is the process of dividing a program into independent, interchangeable modules.
Each module performs a specific function and can be developed, tested, and maintained separately.
Analogy- Think of modularization like building a car.
- Each part (engine, wheels, seats) is designed separately but works together to create a functional vehicle.
Benefits of Modularization
- Easier Testing: Test modules independently before integrating them.
- Improved Reusability: Use modules across different projects.
- Simplified Maintenance: Update or fix specific modules without affecting others.
