🌊 C Odyssey

A roadmap for learning C programming.

The Roadmap

00 Prep Work

Coming from Python ? Start here.

• Understanding why C doesn't have append() or automatic memory.
• Read: Python Vs C Programing

01 Basics

The absolute building blocks

• Variables, printf, scanf, simple math, ASCII.
• Check out: BMI Calculator, Temperature Converter.

02 Control Flow

Teaching the computer to make decisions.

• if-else, switch statements, loops (for, while).
• Check out: Leap Year Checker, Pattern Printing (Floyd's Triangle).

03 Number Logic

Algorithms involved in integer properties. Good for interview prep.

• Modulo operator, digit extraction, base conversion.
• Check out: Armstrong Numbers, Binary ↔ Decimal, Number to Words.

04 Arrays

Handling lists of data

• Indexing, memory layout, bounds checking.
• Check out: Reversing arrays, Finding Min/Max.

05 Searching & Sorting

Classic Computer Science algorithms you need to know.

• Efficient data retrieval and organization.
• Check out: Bubble Sort, Binary Search, Merge Sort.

06 Pointers & Memory

The "scary" stuff (that isn't actually that scary if you pay attention).

• Memory addresses, dynamic allocation (malloc/free), pointer arithmetic.
• Check out: Custom atoi/itoa, Sparse Matrix Compression.

07 Mini Projects

Putting it all together into something usable.

• Tic-Tac-Toe: Full game logic with 2D arrays.
• Number Guessing Game: Random generation and loops.

Running this

I used a Makefile to keep things simple. No need to type gcc manually for every program.

1. Clone the Repo:

   git clone https://github.com/TheTimelessRecall/C-Odyssey.git
   cd C-Odyssey

2. Compile everything:

   make

   This creates a bin/ folder with all your executables inside.

3. Run a program:

   ./bin/tic_tac_toe

   (Or whatever program you want to run)

4. Clean up:

   make clean

Where to Learn C

Course

• CS50x (Harvard): The gold standard. It is free, difficult, and covers the computer science concepts

Youtube Playlist

• Jacob Sorber: A computer science professor who explains exactly what happens in memory
