How to Learn C - 10 Bootcamps to Get You Started
What you need to know about C
C is a minimalist coding language that was developed by Dennis Ritchie in 19721. Ritchie created C in Bell Telephone Laboratories as a system implementation language for developing the UNIX operating system2. While it is one of the most widely used systems programming languages3, C is also a high-level language for general-purpose use. C's structured, procedural nature makes it not only easy to learn but also robust enough to implement into state-of-the-art software. There are many opportunities to learn C through the comprehensive list of courses, bootcamps, and certificate programs offered below.
What is C used for?
C is useful in developing a host of applications because it produces code that performs almost as fast and efficiently as those written in assembly language.
C is the preferred coding language when developing the following applications:
- Operating systems
- Network drivers
- Language compilers
- Embedded systems
- Many other mission-critical utilities
While C is a mid-level language, it is also considered a foundation language. Once you grasp the fundamentals of C programming, it's easier to understand other languages and applications based on its concepts.
Why learn C?
C is an elegant, simple language that is compact, efficient, and fast. One benefit of learning C is that it helps the programmer understand the underlying architecture and fundamentals of computer theories such as pointers, memory management, and allocation. C powers a large portion of the world's technical infrastructure, such as OS kernels, web browsers, and language interpreters, so it's a highly recommended language for those who want to work on state-of-the-art projects or who want to understand how computers work in general.
Because C has a clean style, a simple set of keywords, and low-level access to memory, programmers can write more efficient code. The language also has a powerful library of in-built functions that can be extended by added features and functions.
Who should learn c?
C is an excellent language for those who plan to build an application that is more resource-intensive than a simple web app. Learning C is also imperative for programmers who want to develop applications where it is necessary to have fine-grained control of the computer and its underlying resources.
Knowledge of C is useful when an application must implement lower-level programming elements such as:
- Pointer-driven memory allocation
- Template expansion
- Address alignment
- Multi-thread data races
- Approximate machine implementation of algorithms
C is necessary for developing applications at the cutting-edge of optimized processor and memory utilization such as games, operating systems, embedded systems, IoT devices, compilers, and network drivers.
What jobs can you get with C?
Generally, the jobs that require the knowledge of C programming language fall within the software developer and software engineer category. Although C is essential for computing throughout the world, it is mostly used for low-level software development. As a result, jobs needing C programming experience are at organizations that develop or maintain applications that need micro-optimization and fine-tuning and that afford to compromise on performance. According to Indeed.com, C developers in the United States earn an average annual salary of $106,320.
What are libraries in C?
C's library consists of a set of named functions. These built-in functions are grouped to form libraries that perform a specific operation in C like handling input/output. The C library is commonly referred to as the C standard library, and it is composed of static and dynamic libraries. These functions are provided so development doesn't have to reinvent the wheel each time they perform a basic operating system task.
Header files are where all of the C standard library functions are stored, and these files are denoted by names such as stdio.h, string.h, stdlib.h, and so on. The GNU C Library Reference Manual can be found here.
What are frameworks in C?
A framework is a conceptual structure that supports the development of software applications. Frameworks include a compiler, code libraries, and other necessary tools. The difference between a framework and a library is the flow of control: with the former, the flow of control is dictated by the framework; with the latter, the flow is dictated by the developer.
C frameworks are generally considered libraries because they don't support object-oriented programming. Neither do they need the full-fledged tools and development support that web applications require. OpenGL and TCP/IP are examples of two "frameworks" that are used with the C language.
Learn C at bootcamp
You can learn C through platforms like edX. Attending a bootcamp that teaches C is also a great way to kickstart a career in coding. You can use our comprehensive list to find bootcamps that include C in their curriculum.

Learn coding from a Silicon Valley tech academy through remote classes from the Lambda School. Choose between a 30-week full-time bootcamp or a 12-month part-time course. The school’s deferred tuition model allows students to attend for free, paying nothing back until they’re making at least $50,000 a year.
The pros were relevant content, experienced instructors, great network, many opportunities. Working to solve real world problems. The cons were that it changes often, sometimes not for the better. Removed TLs which were a part of many people's journey.
Great Academy that gives a full stack course of Java with great teachers, best of them (Hall of Fame): Eivydas, Rūtenis, Mindaugas. Great support from teachers. Maybe a bit disorganized but teachers compensated for it. Course is as difficult as it has to be and that works very well. Provides...
Holberton School offers two-year, full-stack software engineering training in San Francisco, CA; New Haven, CT; Bogota, Medellin, and Cali, Colombia; and Tunis, Tunisia.
Holberton has no formal teachers or courses. Holberton's education is instead delivered through a project-based learning curriculum, where instead of passively learning through lecture and repetition, students learn hands-on through increasingly difficult coding projects.
Students at Holberton also practice peer learning, where they learn to cooperatively work through and support each other...
