It is important to keep the following points in mind while programming in C. Following these rules would help you gain an upper edge over programmers who follow the conventional method and fail to think out of the box. Since the C programming language offers a lot of features, it is up to us if we make the best use of it or not.
Tips to improve your coding skills for C
1. Follow the latest rules in the C Standard compiler documentation rigorously. For instance, according to the latest C standards, it is mandatory to use the int data type before the main function and with return 0. Earlier, people generally used the void data type before the main function. It is an obsolete practice and hence one should avoid using it.
2. Use logical variable names to avoid any confusion.
There are some common identifiers we use to implement some of the most basic concepts.
For instance,
- We generally use the lowercase ‘i’ alphabet is as an identifier while looping in C.
- We usually use the identifier “temp” as a temporary variable to store the value of a variable in certain situations. For example, swapping two numbers involve the use of the “temp” variable.
- We generally use the identifier ‘flag’ as a signal to carry on the next process. It generally holds a boolean value, that is, 0 or 1, or true or false.
3. The use of fgets() proves to be safer than gets() function. The gets() function is prone to buffer overflow that may cause your program to behave anomalously.
4. The proper use of escape sequences like \t or \n improves the readability of your code. Be liberal while using them as proper indentation is a good programming practice. Instead of simply using white spaces, it is better to use escape sequences as they help in displaying the output with standard formatting.
5. Make use of functions whenever the code seems too long and the task that we need to perform is operation specific and multiple. Piling up everything into the main function is absurd. Functions in C helps you to overcome this problem plus it reduces the code redundancy.
6. Don’t use shorthand notations excessively if you aren’t quite familiar with it. Sometimes, it becomes difficult to comprehend.
7. The use of comments in C is a very good practice. It helps you better understand your code. Sometimes, it happens that we write create complicated functions to ease out certain tasks but we end up forgetting their purpose. Hence, it is very important to make the best use of comments to ease our things.
8. Proofread your entire code before compilation.
9. Always save your program before compilation and be careful while giving looping statements. In case your program enters into an infinite loop, you would lose your code.
10. Be careful of syntax and semantic errors.
Steps to Improve Coding Skills for C Language
After reading the C programming best practices, it is now important to develop good coding skills. A good programmer not only follows the best programming practices but also knows how to logically approach a given problem at hand.
The following steps would help you improve your coding skills:
- Read the given problem and understand it clearly. It is of utmost importance to clearly comprehend the problem given to us. If you have a vague understanding of the problem, you cannot develop a heuristic approach to solve the problem.
- After clearly understanding the problem, analyze it and list out the various approaches that you think are feasible to solve the problem.
- After listing out the feasible methods to solve the problem, consider all factors in mind and choose the optimal approach that keeps your code as simple as possible. While doing this, keep in mind all the inbuilt functions that might come in handy to solve the problem.
- There are a lot of algorithms available on the net to approach various problems. Either use a pre-defined algorithm to solve the problem or develop your own.
It is preferable for new programming enthusiasts to study and analyze the pre-existing algorithms that have been proposed years ago by proficient programmers and developers. After developing a basic understanding, you may proceed towards building your own. - Don’t be afraid of trial and error. If you are working on a complex program, whenever you are storing modifiable values in temporary variables, use the printf() statement to check the intermediate values to be sure if you’re on the right track.
- Always remember, logic does not come out of anywhere. It comes through persistent practice and eagerness to learn and explore more and more.
- Focus on the fundamentals first because they would always be there with you. Jumping to advanced problems with a vague and ambiguous understanding of the basics and expecting to master the art of programming is like building castles in the air.
- Don’t be afraid of mathematics. Keep in touch with mathematics as it is the base of solving most of the programs that we might encounter while applying for programming job interviews or designing your own application.
- Be sure to take online quizzes to check your fundamentals.
- Instead of focusing on several programming languages, focus on one completely. We usually prefer C and C++ when it comes to the implementation of data structures and algorithms as we generally write them in C/C++.
If you’re preparing for a C language tutorial then you’ve landed at the right spot. Learn from the best C programming tutorials and also prepare for c language questions and answers for interviews for freshers and get market-ready with your skillset. Let’s get started with the most asked and basic questions first to help you become ready to kickstart your career.
