C

C is a low-level programming language used for operating systems, embedded systems, performance-critical libraries, and language runtimes.

What Is C​

C gives direct control over memory and hardware-oriented behavior.

It is small, fast, and influential, but it requires careful memory management.

How To Use C​

Install a C compiler such as GCC, Clang, or MSVC. Write a .c file, compile it, and run the generated executable.

Basic Example​

#include <stdio.h>

int main(void) {
    printf("Hello, C\n");
    return 0;
}

Common Concepts​

  • Pointers store memory addresses.
  • Header files declare shared functions and types.
  • Manual memory management uses functions such as malloc and free.
  • The compiler turns source code into machine code.

What To Learn Next​

Learn pointers, arrays, structs, memory allocation, build tools, and debugging with tools such as gdb.
