Stepping into Refactoring Code

Welcome to our captivating session on refactoring, a powerful tool for tidying up code, much like organizing a toolbox for efficiency.

In C++, each line of code is akin to a foundational component in a complex system, and poorly organized code can lead to unwieldy and unstable software. Today, we'll focus on enhancing the readability, maintainability, and performance of our code through refactoring.

Recapping Crucial Concepts

Let's briefly revisit a few key concepts:

  • Code Smells: Indicators that our code needs refactoring, such as tangled dependencies or redundancy that call for cleanup.

  • Refactoring Techniques: We've familiarized ourselves with Extract Method and Rename Method techniques in earlier lessons, using C++ functions and member functions to maintain clarity and abstraction.

  • OOP in Refactoring: We've harnessed Object-Oriented Programming principles to enhance our code's structure.

  • Code Decoupling and Modularization: Methods to manage code by minimizing dependencies while organizing through header and implementation files.

We'll use these concepts as guiding stars as we journey through the refactoring process in C++.

Practice Problem 1: Taming a Complex Function

Let's begin by refactoring a complex game score computation function. Observe the initial scenario in C++:
