How do you ensure that you as programmer have written quality C code?

Question

I m looking to write some quality C code. Can someone point me to some articles , websites..whatever I need something with examples. I have already seen and read K&R C book.

But times have changed, some one must have more to say on quality C Code. and another important thing is How do you ensure that you as programmer have written quality C code??

Answer 1

Someone mentioned some compiler switches, but having syntactically smooth code is not going to ensure a quality end-product, because there's more to software quality than that.

There are several classifications of software qualities, but here's a list that you can use as a checklist:

• Correctness (does it work according to spec?)
• Reliability (can de user depend on it?)
• Robustness (does it work in unexpected situations?)
• Performance (does it do the job fast enough for the user?)
• Usability (is it user-friendly?)
• Verifiability (can its properties be verfified easily?)
• Maintainability (can modifications be made easily?)
  • Repairability (can defects be fixed within reasonable time?)
  • Evolvability (can new functionality be added simply?)
• Reusability (can the code easily be used in other projects?)
• Portability (can it run easily in different environments?)
• Understandability (can maintainers easily understand it?)
• Interoperatability (how well does it cooperate?)
• Productivity (efficienct and performant delivery)
• Timeliness (ability to deliver on time)
• Visibility (are all steps documented clearly?)
