Best Online C Programming Courses and Programs (2024)

Why learn C programming?

C is over 50 years old, and many modern languages are considered easier to learn and use. So why is C programming still considered an essential skill for computer scientists?

One reason is speed. As a middle-level language, C is a compiled language and can perform quicker than interpreted languages like Python on certain tasks. Learning C programming also provides a strong foundation for learning other languages.^{Footnote 4}

Once you know C, learning the syntax of other programming languages can feel easier. C is also particularly versatile; you can write and compile C code on almost any computer. This makes it a kind of universal language for discussing programming concepts.^{Footnote 5}

What is covered in a C programming tutorial?

The curriculum you pursue or type of C programming course you choose to take should reflect your level of experience.

In a beginner course for those with limited programming experience, learners may focus on a few simple programs to introduce them to C programming syntax. This includes C programming fundamentals, such as the basic C functions, operators and conditionals, loops and errors, arrays and strings, and pointers and memory. From there, learners can move on to more advanced topics such as multithreaded programming.^{Footnote 6} A strong foundation in mathematics and programming can prepare you to succeed in a C programming course or coding boot camp.

Some bachelor’s programs in computer science may include C programming as a required course. Similarly, if you want to pursue a master’s program in data science, you will likely draw on C extensively since it is widely used in the field.

Jobs in C programming

A trained C programmer may work in numerous fields, including scientific research, software engineering, and data science.

Software engineers work on developing applications and operating systems, collaborating with multidisciplinary teams including UI/UX designers and data scientists. Meanwhile, data scientists use coding to analyze data sets and provide insights, and their work is integral to machine learning. The versatility of the C programming language makes it a valuable asset in these professions and more.

Every job and its requirements vary. For some, a bachelor’s degree or a master’s degree in a technical field such as computer science may be required to apply. Other positions may accept a background that includes a boot camp or short course experience.

How to become a C developer online

Knowledge of C can help you become proficient in other development languages and set you up for a career in software or web development. There are many online C programming courses that can provide you with an understanding of C programming techniques.

Some of these programs will offer you a professional certificate as proof of proficiency in C. However, this certificate alone does not necessarily guarantee you a job as a C developer. As mentioned, some jobs may require degrees from institutions of higher education, and many will require a portfolio of prior work. Your portfolio should demonstrate that you have an understanding of C programming techniques and have gone beyond your training to demonstrate creativity and commitment.^{Footnote 7}

What is C programming used for?

C programming techniques are used to design operating systems, graphical user interfaces, compilers, and databases. C is also used in embedded systems found in many common machines, including microwaves, vending machines, credit card readers, and even cars. The versatility of C makes it a valuable tool for any programmer, especially as they interact with legacy systems and older code.

Is C programming hard to learn?

C is often considered more difficult compared to modern programming languages because of its complex syntax. It also lacks many features that are standard in modern programming languages. However, once you learn C, you may be able to apply your new knowledge and strengthen your skills across other development languages.

How long does it take to learn C programming?

How long it takes to learn C programming will depend on which path a learner takes and how much time they want to devote to their studies. A basic, introductory C programming tutorial may last under 24 hours, and a boot camp offering a graduate certificate may last a few months. A bachelor’s degree will usually take four years to complete. Most master’s programs last two years.

What are the applications of C programming?

C is used in developing operating systems, graphical user interfaces, embedded systems, compilers, and databases. It can, however, be used for almost any programming purpose, due to its versatility.

Should you learn C or C++?

C++ is a language derived from C with a similar syntax, but the difference is it includes object-oriented programming features such as classes and objects.^{Footnote 8} Both will provide you with a strong foundation for learning other programming languages. However, as a middle-level language, C is closer to the machine assembly language, so it may be a better choice for working on fundamental software like operating systems.
