A modern-day classic on software engineering, Code Complete focuses on specific practices you can use to improve your code and your ability to debug it--and ultimately deliver better, more efficient programs in less time. With every bit of advice the book proffers you'll improve your ability to write elegant, self-documenting, maintainable software. McConnell doesn't focus on the idiosyncrasies of any single language, but on the general issues developers face: naming subroutines and variables in meaningful ways, designing control structures, finding and correcting errors in code, and many, many more. Code Complete is packed with code samples demonstrating good and bad programming practices and checklists that you can use to vet your own work.
