    Introduction

    C is a procedural, compiled language. You author text source files, a toolchain turns them into machine code, and the operating system loads the result. The language exposes memory and CPU details that many modern languages deliberately abstract away.

    Understanding the topic

    Typical C deployments:

    • Operating-system kernels and device drivers
    • Microcontrollers and firmware
    • Language runtimes, databases, and network stacks
    • High-performance libraries and game-engine cores
    • Legacy enterprise codebases maintained for decades
    ArtifactRole
    .c sourceImplementation you edit and compile.
    .h headerShared declarations included with #include.
    CompilerTranslates C into object code (gcc, clang, MSVC).
    LinkerJoins objects and libraries into one executable.
    Process startOS launches the binary; control enters main().

    Informative example

    Smallest useful program:

    c
    #include <stdio.h>
    int main(void) {
    puts("TechLearningPRO — C ready.");
    return 0;
    }

    Author

    Create a .c file with headers and main().

    Summary

    C trades automatic safety nets for speed and control — ideal when you need to reason about hardware and memory directly.
