The principles of good programming are closely related to principles of good design and engineering. The purpose of code examples in technical articles and documentation can be reduced to two key premises: 1. to illustrate a concept or idea, or document the syntax of something 2. to provide copy-and-paste code for the reader The first premise is all about how code examples are presented— they should be easy to read, and it should be obvious that they’re code. List the principal diagnosis, condition, problem, or other reason for the medical service or procedure. Duplication is the root of all software evils. When I started my adventure with programming in C language, I wrote complete spaghetti code. This also saves … Flow is a psychological state that you get into when you’re absorbed in your work (sportsmen call it being “in the zone”).  Have you ever gotten really into your work, so much so that suddenly an hour has passed without you noticing?  That’s flow!  In this state, you tend to be very productive and very focused on the task at hand.  Therefore, you want to try to stay in this state for as much of the time as possible.  It can take as much as 15 minutes to get into the flow, so it’s important to minimise things that will pull you out of the flow (once you’re out, that’s 15 minutes largely wasted).  That means try to avoid distractions, turn off the e-mail alert beep, listen to music to block out background noise, turn off your web browser.  Whatever it takes! They work by ‘asserting’ that something is true and if it isn’t then the program stops. Discover the concepts of computer programming and practice writing programs in Principles of Coding, an AOA elective for students in grades 7 and 8. Here you’ll find support for teaching and studying the BTEC Specialist Level 3 qualification for Principles of Coding for Digital Marketer Level 3 Apprenticeship Standard. If all you have is a hammer, then all your problems tend to look like nails.  The way to avoid this is to have more than one tool.  In general, you want to have a good, broad selection of tools with which to write your code.  A good way to acquire this is to try to learn the occasional new tool as you go along.  These can be useful pieces of software, new techniques or whatever; the important thing is that it gives you at least one more good option for writing your code. Learn the Basics of Python Programming online with Python Principles. Principles of Coding. You should not forget that writing a program is self-discipline. All the above points don’t take much effort, once you get used to them, and the time (and headaches!) As much as possible, test your code as you write it.  These tests will often be quick and easy ones, such as checking that the value of pi you’re using is really what it should be, but if you perform these little checks while you’re working on (and thinking about) that piece of code, you’ll save yourself a lot more effort having to come back later and fix bugs.  You’ll find that you can perform a lot of simple tests very quickly as you go along; once you’re in the habit, you really don’t spend a lot of time doing it.  But the time you save yourself later on can be considerable. ), avoiding global variables (with the possible exception of explicitly fixed constants such as PI) and the like.  If you’re feeling keen, writing object oriented code is excellent for this, as this has encapsulation built into the process. Principles of Coding and Reimbursement for Surgeons will be of great value to general surgeons and surgical subspecialists in private practice, academic institutions, and employed … Learn 1 coding principles with free interactive flashcards. Lets Rule Out any sort of dependencies or minimize it if not possible to rule out completely. In programs with a GUI (Graphical User Interface) this usually means there is a catch-all at the user interface layer that displays a message to the user (or something similar) before attempting to save the data and then shutting down. When someone glances at a chunk of code, they can often form a quick impression of what that chunk of code does.  It is convenient when this impression is accurate; it can be a real problem if the impression is misleading and they makes changes to the code before they realise.  The ‘principle of least surprise’ is that you should try to make your code’s actual functionality as close as possible to the typical quick impression.  Or, to put it another way, you should try to write your code so that it communicates its functionality accurately in a very short (pain-free) amount of time.  This means doing things like picking informative variable/function names, writing informative (and succinct) comments, and making the layout easy to read. The simpler your code is, the easier it is to construct and maintain.  So, subject to the constraints of our objectives, the simpler you can make your code the better.  This has a connection to premature optimisation (see this post ), because optimised code tends to be less simple.  We think a reasonable rule-of-thumb is that unless most simple way of doing something will be obviously too inefficient, it’s worth trying.  you can always change it later and, because it’s simple code, this shouldn’t be too hard.  One way to describe this is to paraphrase Albert Einstein:  Code should be as simple as possible, but no simpler. Amazing Image Hover Effects of Advanced CSS3, What Does It Take To Become An Intermediate Programmer From Beginner, Popularity of Programming Languages: January 2009. Tools can help you in various needs i.e. Learn new tools and use then frequently. Here also, I did the same thing. Once you start to leave one or two things unfixed, it becomes much easier to leave “just one more”, and soon your code is a wreck.  There should not be a single “broken window” in the code you’re building (the phrase “broken window” comes from a study that showed that a major indicator of the state of a building was a single broken window; once one is broken, people care a lot less about maintaining the rest, it seems).  The book “The Pragmatic Programmer” has a nice description of this.
