Clean Coding.....Keep It Your Code Clean

Introduction:

Anyone can write a code that computer can understand but the only good programmer can write a code that human can understand. Clean code is simple and direct. Clean code reads like well-written prose. Clean code never obscures the designer’s intent but rather is full of crisp abstractions and straightforward lines of control. Clean code can be read, and enhanced by a developer other than its original author. It has unit and acceptance tests. It has meaningful names. It provides one way rather than many ways for doing one thing. It has minimal dependencies, which are explicitly defined, and provides a clear and minimal API. Code should be literate since depending on the language, not all necessary information can be expressed clearly in code alone.

“Clean code is a set of rules and principles that helps to keep our code readable, maintainable, and extendable. It's one of the most important aspects of writing quality software. It is a reader focused development style that produces software that easy to write, read and maintain”.

Benefits of Clean Code:

• Easily to understand the code
• Easy to understand the logic
• Improve Code maintenance
• Easy Testing and Debugging
• Name and name spacings are useful
• Reduce programmer time to spend for understanding
• Identify the principles and practices
• Easy to changeability and Extensibility
• Good Impression to the customers
• Descriptive, Consistency and Abstraction based

Qualities of Experienced programmers:

• Always they have a plan
• Improve algorithm and problem-solving skills
• Delete unnecessary code
• Keep consistent code style
• Write good comments
• Proper testing, Debugging and documentation process

Bad Code:

The code containing an inappropriate names and logics for the object and its members is called bad code. The bad code may be correct as far as compiling and execution. Bad code creates issues in development, debugging and modifying the coder. It may lead to financial losses.

Difference between Good Code and Bad Code:

Bad Code:

• Inappropriate names and Logic for object.
• It leads Financial Losses.
• Problems while execution
• Slow run time and longer debugging time
• Rigid code structure
• Code duplication
• Lower maintenance

Good Code:

• Fast run time
• Shorter debugging time
• Easy to modify and reusable
• Simple structure and readable
• Reduced total cost of ownership
• Easy to find fault
• Without duplications and Elegant

Code Standard:

Code standards are collections of coding rules, guidelines, and best practices. Each programming language comes with its own coding standards, which should be followed in order to write cleaner code. Best Coding Standards are follows,

• File Organization
• Programming principles
• Code Formatting
• Name Conventions
• Comments

Clean Coding – Guidelines to Write Better Code:

• Give meaningful names to variables, functions, classes, and other entities in the code.
• Create functions that are small and do a single thing.
• Encapsulate related data and functions into small independent classes.
• Structure the code for better readability. Keep related code together and keep the lines smaller.
• Enhance readability with proper comments.
• Write readable, fast, independent, and repeatable tests.
• Avoid Unnecessary functionalities.
