What do we call the set of rules that must be followed when writing a program in a specific programming language?

Coding standards are collections of coding rules, guidelines, and best practices. Using the right one — such as C coding standards and C++ coding standards — will help you write cleaner code.

Here we explain why coding standards are important, so consider this your guide to finding and using coding rules and guidelines.

What Are Coding Rules and Guidelines?

Coding rules and guidelines ensure that software is:

  • Safe: It can be used without causing harm.
  • Secure: It can’t be hacked.
  • Reliable: It functions as it should, every time.
  • Testable: It can be tested at the code level.
  • Maintainable: It can be maintained, even as your codebase grows.
  • Portable: It works the same in every environment.

Why Are Coding Standards Important?

The reason why coding standards are important is that they help to ensure safety, security, and reliability.

Every development team should use one. Even the most experienced developer could introduce a coding defect — without realizing it. And that one defect could lead to a minor glitch. Or worse, a serious security breach.

There are four key benefits of using coding standards:

1. Compliance with industry standards (e.g., ISO).

2. Consistent code quality — no matter who writes the code.

3. Software security from the start.

4. Reduced development costs and accelerated time to market.

In embedded systems industries, these standards are required (or highly recommended) for compliance. This is especially true for functional safety standards, including:

  • IEC 61508: “Functional safety of electrical/electronic/programmable electronic safety-related systems”
  • ISO 26262: “Road vehicles — functional safety”
  • EN 50128: “Railway applications — Communication, signaling, and processing systems — Software for railway control and protection systems”
  • IEC 62061: "Safety of machinery: Functional safety of electrical, electronic and programmable electronic control systems"

Each one is written for a specific programming language. Most embedded systems developers use C or C++.

Important C Coding Standards

The C programming language is flexible. It’s also known for high performance. That’s why it’s popular among embedded developers.

But C is also prone to risk. C code can be compiled with undefined behavior. And that undefined behavior opens your code up to vulnerabilities and defects. Or your C code may be unpredictable when it’s ported to different hardware.

Using C coding standards is a smart way to find undefined and unpredictable behaviors.

There are several established standards. Some are specifically designed for functional safety — such as MISRA. Others are focused on secure coding, including CERT.
 


Choosing the right C coding standard can be difficult — but it doesn’t need to be.

Important C++ Coding Standards

The C++ programming language is larger and more complex than C. Like C, C++ is flexible. And it’s recognized for high performance.  

But to have a maintainable codebase, it’s important to use a C++ coding rules. This will help you ensure that undefined and unpredictable behavior stays out of your code.

There are several established standards for C++. Some are specific to embedded industries concerned about functional safety — including MISRA, AUTOSAR, and JSF AV C++. Others are designed for secure coding, such as CERT.

How to Enforce C Coding Standards and C++ Coding Standards With Static Code Analysis

You can have a coding standard — but that doesn’t mean it’s being followed.

Static analyzers — such as Helix QAC or Klocwork — are the best way to ensure that they are enforced. By using automated static analysis, you can ensure your code conforms before you spend time on peer code reviews. Plus, this makes code reviews and testing phases more effective.

What Is Syntax in Computer Programming?

JavaScript 101 is a series of instructional videos given by Devmountain Web Development Instructors. Click here to see the entire video series. 

We refer to syntax in computer programming as the concept of giving specific word sets in specific orders to computers so that they do what we want them to do. Every programming language uses different word sets in different orders, which means that each programming language uses its own syntax. But, no matter the programming language, computers are really exacting in how we structure our syntax. In this video, you’ll understand what syntax is in programming and how it’s important in getting a computer to do what you want it to do.

Video Transcription 

Once we figure out what we want the computer to do, we need a way to communicate to give it the instructions so that it can do it correctly. This is where we’re going to write the code part of coding.

What is Syntax in Programming?

Syntax is the set of rules that define what the various combinations of symbols mean. This tells the computer how to read the code. Syntax refers to a concept in writing code dealing with a very specific set of words and a very specific order to those words when we give the computer instructions. This order and this strict structure is what enables us to communicate effectively with a computer. Syntax is to code, like grammar is to English or any other language. A big difference though is that computers are really exacting in how we structure that grammar or our syntax.

This syntax is why we call programming coding. Even amongst all the different languages that are out there. Each programming language uses different words in a different structure in how we give it information to get the computer to follow our instructions.

Web developers primarily focus on HTML, CSS, and JavaScript. That is what we’re going to focus on in this course as well. By focusing on these languages and mastering them, you’ll be able to write websites that can be opened by any browser in the world.

Programming Syntax Examples

To explain syntax further, we’re going to define syntax as essentially a set of keywords and characters that a computer can read, interpret, and convert into tasks that it knows it needs to do. Programming or coding is typing these keywords and these characters into a file in the right order and feeding it into the browser. The browser then processes our information, if it’s in the right order, it then can figure out how to execute the task that we want it to do.

Think of syntax like the drive-through at a burger joint. If you can do a few simple things in the exact right order, you get what you want. You have to tell them what you want in the microphone, pay at the first window, and pick up your food at the second window. You have to do it in that order. You can’t pay the microphone or pick up your food where you’re supposed to pay. Additionally having this order in place helps you get what you want faster and with less talking.

Because we’ve already agreed how drive-throughs work, you can simply pull up and say, give me number one and expect to get exactly what you want. That’s the benefit of having preset syntax.

Computers Can’t Read Typos

The flip side of syntax is that computers are going to be exact in what they expect us to code. Humans are not so precise. We can read someone else’s typo and infer what they meant and move right along. If a computer finds a typo, it’s gonna get confused and lost, and have no idea what you meant it to do. This might get you pretty anxious about all the mistakes you can make on a computer. It’s nothing to get worked up about. If you make a mistake, your computer is not going to crash and catch on fire. It’s simply gonna say, “This doesn’t work.” You fix the error, you try again.

If you forget something, there’s a lot of online guides and references that you can look up to find the syntax that you’re missing. So don’t get worked up about it.

Let’s move on to some more exercises so that you can practice this and start getting more familiar with syntax.
