C is a low-level, procedural language. Unlike high-level languages that hide the computer's inner workings, C gives you direct control over memory and hardware. This makes it incredibly fast and efficient, which is why it is used to build operating systems (like Windows and Linux), game engines, and embedded systems in cars or appliances. Core Building Blocks To write C, you need to understand four basic concepts:

: Computers cannot read C code directly. You use a tool called a compiler (like GCC or Clang) to translate your text into machine-readable instructions. The Development Cycle Writing in C follows a specific three-step loop: Coding : Writing the logic in a .c file.
