C Programming: Modular Programming and Memory Management
C Programming: Using Linux Tools and Libraries
What is C?
The C programming language was created by Dennis Ritchie in 1972. A low-level procedural language, C is designed to work across platforms and provide access to important features like memory management. C programming builds up the source code for many UNIX operating systems, compilers, video games, and even other computer programming languages like Python. Although it lacks more modern programming features like object-oriented programming, C remains one of the most widely used general-purpose programming languages in the world with broad applications in computer science and software engineering.
C Programming Online Courses and Tutorials
C is an excellent language to learn if you want to get into the nitty gritty of computers and software development. You can start with zero experience and learn C programming online from top institutions on edX to understand everything from basic printf statements to more complicated concepts like algorithms, memory allocation and compilers.
Harvard's popular CS50: Introduction to Computer Science uses the C programming language to give newcomers a comprehensive overview of programming concepts and computer science topics such as data structures, recursion, conditionals, ansi, data types, and algorithms. Dartmouth's C Programming language courses are also helpful for beginners to learn about specific details of the C language such as syntax, gcc compilation, standard library functions, bitwise operations, and specifiers.
Once you've completed the basic C programming courses, up your game by mastering more advanced material. Dartmouth's C Programming with Linux gets you familiar with the command line and contextualizes the C programs you write in the context of the Linux operating system. UTAustin also offers hands-on learn-by-doing courses that show you how to apply the C programming language and write C code to build real-world systems and gadgets.

History of C programming language
The C programming language dates back to 1972. A successor to the B programming language, C was developed by Dennis Ritchie to build tools for Unix. C code eventually came to underpin the entirety of the Unix operating system, and starting in the 1980s, the language grew to become one of the most popular programming languages in the world.
In 1989, C became standardized by the American National Standards Institute (ANSI) and International Organization for Standardization (ISO). C remains one of the most efficient general purpose programming languages and has been used to build many compilers, computer architectures, operating systems, video game engines, and even other programming languages. According to the TIOBE index in January 2021, C is considered the most popular programming language today.
