Part 1

Module 1: Foundations, Syntax & Primitives

Compilation pipeline (cpp/gcc/ld), main() anatomy, primitive memory sizes, operators, booleans (<stdbool.h>), and control flow.

0 / 5 completed

01.C Introduction, Compilation Pipeline & Syntax

Discover why C powers modern operating systems and master the 4-stage compilation pipeline.

Start

02.Variables, Primitives & Explicit Type Casting

Master memory footprints of int, float, double, char, the sizeof operator, and type casting.

Open

03.Operators, Precedence & Booleans (<stdbool.h>)

Master arithmetic, relational, and logical operators with C99 boolean types.

Open

04.Control Flow: If-Else, Ternary & Switch

Master multi-branch conditional execution and jump-table optimized switch statements.

Open

05.Loops (For, While, Do-While) & Jump Statements

Master loops, break, and continue for high-efficiency repetitive execution.

Open

Part 2

Module 2: Arrays, Strings, Input & Pointers

Contiguous arrays, null-terminated strings (<string.h>), safe user input (fgets), memory addresses (&), and pointer dereferencing (*).

0 / 4 completed

06.Contiguous Arrays & Multi-Dimensional Matrices

Understand contiguous memory layout, bounds overflow dangers, and sizeof element calculations.

Open

07.Null-Terminated Strings & <string.h>

Learn how C represents text as null-terminated char arrays (\0) and use string functions safely.

Open

08.User Input, scanf & fgets Buffer Safety

Master console input with scanf and fgets while preventing buffer overflow exploits.

Open

09.Pointers, Memory Addresses & Dereferencing

Master memory addresses (&), pointer variables (*), dereferencing, and pointer arithmetic.

Open

Part 3

Module 3: Functions, Recursion, Files & Structs

Function prototypes, pass-by-pointer, function pointers, file streams (fopen/fclose), structs, unions, and memory word alignment padding.

0 / 5 completed

10.Functions, Prototypes & Pass-by-Pointer

Structure modular C code with function prototypes and mutate state via pass-by-pointer.

Open

11.11. Recursion & High-Speed Function Pointers

Master call-stack recursion mechanics and first-class function pointer callbacks for qsort.

Open

12.File Streams: Create, Write & Read (fopen/fclose)

Learn standard I/O file streams using FILE*, fopen modes, and stream buffer safety.

Open

13.Structures, Unions & typedef Aliasing

Define compound data types using struct and typedef, and master dot (.) vs arrow (->) access.

Open

14.Memory Word Alignment & Struct Padding

Learn how CPU memory word boundaries insert invisible padding and how to optimize layout.

Open

Part 4

Module 4: Dynamic Memory, Bitwise & Errors

Bitwise masks (flags), dynamic heap management (malloc/free), error handling (errno/strerror), and preprocessor macros.

0 / 4 completed

15.Enums & Bitwise Manipulation (Flags & Masks)

Master enumerated state types and low-level bit manipulation using bitwise AND, OR, XOR, and shifts.

Open

16.Dynamic Memory: malloc, calloc, realloc & free

Manage heap memory manually using malloc, calloc, realloc, and prevent memory leaks with free().

Open

17.Defensive Error Handling, errno & Assertions

Handle system failures defensively using errno, strerror, perror, and runtime assert macros.

Open

18.Preprocessor Macros & Storage Classes

Master parameterized macros, header guards (#ifndef/#endif), and storage classes (static, extern).

Open

Part 5

Module 5: Standard Libraries & Capstone Engine

Fixed-width integers (stdint.h), math, time, and building an in-memory key-value database engine from scratch.

0 / 2 completed

19.Fixed-Width Types (stdint.h), Math & Time (<time.h>)

Write robust portable C using exact-width integers (uint32_t, int64_t), math, and system epoch timestamps.

Open

20.Capstone: High-Performance In-Memory Key-Value Engine
