What is C programming?
Created in the 1970s by Dennis Ritchie, C is a powerful and popular general-purpose programming language.
Used for a variety of projects, C powers operating systems like Windows, Linux, and Mac, as well as many databases and automotive technologies. Even projects that use other languages often require C compilers.
Benefits of learning C programming
- Popularity: C is an extremely popular and widespread programming language, so programmers with C on their résumés enjoy high demand.
- Variety of applications: With knowledge of C, you can work on operating systems, automotive technology, and a wide variety of other projects. Programmers who enjoy diversity in their work should pursue C.
- Low-level language: C is a low-level language, which means it operates close to the computer's hardware. Compared to high-level languages like Python and Java, low-level languages like C allow the programmer to interact directly with hardware features like memory.
- Simplicity: Compared to other programming languages, C uses a relatively simple syntax and a small set of keywords. The language is ideal for beginners, and experienced programmers can pick it up relatively quickly.
