Before writing C code, you need to understand programming logic, variables, data types, and the basics of using the terminal and an editor. In this episode you will also set up the gcc or clang compiler, build tools, a debugger, and verify your toolchain for the first time.

This episode traces C's birth at Bell Labs by Dennis Ritchie, its role in developing Unix and operating systems, and the evolution of the C89, C99, C11, C17, and C23 standards. You will also understand the problems C solves and when to choose C over other languages.

This episode digs into what happens behind the scenes: the four-stage compilation process, the C memory model that divides the stack, heap, static data, and text segments, and the ABI and calling convention. You will also see the structure of a C program and the toolchain flow.

This episode builds the foundation of C syntax: variable declarations and basic data types, a complete program structure with the main function, statements, code blocks, comments, and formatting rules. You will also assemble, run, and do some simple debugging.

This episode masters all of C's operators: arithmetic, bitwise, logical, comparison, and ternary. You will also practice the if, if-else, and switch conditional statements, all three loop types, and break, continue, and return as control flow tools.

This episode builds functions as modular units: definitions and prototypes, variable scope, passing parameters by value, and return values. You will also assemble multi-file programs with header files, and get to know recursion, inline functions, and function pointers.

This episode expands C's data type toolkit: one- and multi-dimensional arrays, strings as character arrays, struct, union, and enum as composite types, plus typedef for aliases that clarify code intent and simple data structures.

This episode dissects pointers, the heart of the C language: memory addresses, dereferencing, pointers to arrays, strings, and functions, dynamic memory allocation with malloc, calloc, realloc, and free, and pointer safety and common bugs like use-after-free and null pointers.

This episode masters C input-output: printf, scanf, getchar, and putchar for standard I/O, then fopen, fread, fwrite, fprintf, fgets, and fclose for file handling. You will also understand file modes and error handling with errno and perror.

This episode builds basic data structures in C: linked lists, stacks, and queues using pointers, then bubble, insertion, and selection sort, and linear and binary search with a simple complexity discussion using Big O.
