The Complete C Programming Notes & Keynote Deck
Exhaustive notes synthesizing the 50-Hour C Mastercourse and Dr. Chuck's K&R Classic C Series. From ground-zero bits, bytes, and memory architectures up to kernel pointers, dynamic heap management, and data structures.
Course Modules Roadmap
Select any module below to open its dedicated presentation deck and complete editorial notes.
Computer Architecture & C Under The Hood
Von Neumann model, CPU registers, ALU, RAM hierarchy, GCC 4-stage compilation pipeline, and 32/64-bit virtual memory layout.
C Language Foundation & Standards
Dennis Ritchie, Bell Labs, C89 to C23 standards, main() signatures, return codes, tokens, keywords, and identifier naming rules.
Data Types, Variables & Binary
Primitive types, <stdint.h> fixed-width types, Two's complement representation, integer overflow rules, and type qualifiers.
I/O Operations Deep Dive (printf / scanf)
printf specifier flags, width & precision, scanf buffer mechanics, newline traps, scansets, and safe input handling.
Operators & Bitwise Manipulation
Arithmetic, relational, logical short-circuiting, bitwise operations, bitmasking recipes, and precedence rules.
Control Flow & Decision Making
if-else branching, nested logic, the dangling else problem, switch-case jump tables, and fall-through mechanics.
Iteration & Looping Constructs
while (entry-controlled), do-while (exit-controlled), for loop internal mechanics, nested loops, and goto error cleanup.
Functions & Storage Classes
Prototypes, pass-by-value vs pointers, auto, register, static, extern, recursion stack frames, and Tail Call Optimization.
Arrays & Multidimensional Matrices
1D array memory contiguity, pointer decay, indexing math arr[i] == *(arr+i), 2D Row-Major Order, and VLAs.
Pointers & Deep Memory Mastery
Address-of (&), dereference (*), pointer arithmetic, double pointers, void* generic pointers, and function pointer callbacks.
Strings & <string.h> Algorithms
Null-terminated strings, .rodata literals vs stack arrays, safe string handling, and custom strlen/strcpy/strcmp.
Dynamic Memory Allocation (Heap)
malloc, calloc, realloc, free, neutralizing dangling pointers, double-free bugs, and Valgrind memory debugging.
Structures, Unions & Memory Alignment
struct member access, CPU word alignment, struct padding, #pragma pack, tagged unions, and hardware bit-fields.
File Handling & Persistent Stream I/O
FILE streams, fopen modes, text vs binary files, fread, fwrite, random access with fseek and ftell, error handling.
The C Preprocessor & Macros
#define function macros, stringification (#), token pasting (##), conditional compilation, and header guards.
Advanced C, DSA & Top 50 Interview Qs
Makefiles, command-line argc/argv, Linked Lists, Stacks, Queues, Binary Trees, and Top 50 Interview Questions with solutions.
