A Quick Look at C Programming

# Lecture 10. C Language Quick Overview

## New Lesson Posting Notice

Hello, students! For this course, **89** new lessons (totaling 12 sections) will be posted sequentially. Since I am producing multiple courses simultaneously, I am proceeding by posting **a little bit of each course alternately**, rather than uploading one entire course at once. Please find the posting principles and the schedule for each section below.

> For your reference, the lessons being posted now are not entirely new content, but are part of the production of **revised editions (2nd or 3rd editions)** that reinforce existing lectures.

## Posting Principles

- Currently, I am rotating through a total of 19 courses in order (rotation method), posting one lesson per course alternately.
- Postings take place on weekdays (Mon-Fri), with 5 new lessons being uploaded daily across all courses.
- For this course, the next lesson will be posted each time its turn comes around in the rotation.
- While the posting speed may seem slow compared to other courses, all courses are progressing together in the same manner.

## Estimated Completion

Based on the current pace, the estimated completion date for all postings of this course is around **August 2027**. (The actual schedule may be moved up or delayed depending on the production progress.)

At the request of our readers, we are issuing a 66% discount coupon for "Cognitive Load Management Techniques to Break Through the Limits of RAG Performance" (the 990,000 KRW course can be purchased for 330,000 KRW).

For your information, this course is currently in the process of posting the 2nd edition, which is a revision of the 1st edition.

In the case of the 2nd edition, all class materials have been posted, but the videos are still in the process of being uploaded.

I post the 2nd edition videos frequently, but it will take a long time (at least several months) to post all of them.

Please keep this in mind and carefully decide whether to use the coupon.

The deadline is the 19th and there is a limited number of coupons available, so please hurry if you need one.

Hello.

The era of AI writing code has arrived.

However, the task of verifying the code written by AI and directing the path for improvement remains the responsibility of humans.

Furthermore, it has become necessary to know how to utilize AI more extensively in both vertical and horizontal directions.

The horizontal direction refers to a direction that encompasses everything from planning to deployment, and

The vertical direction refers to a direction that can encompass various languages, various frameworks, and various methodologies.

Therefore, a developer with a broad spectrum (that is, a complete spectrum in both vertical and horizontal directions)

will be needed.

However, the education system has not yet been able to keep up with this.

That is why I have opened the "Structural Code Reading Bootcamp" using Claude Code.

At https://code-reading-bootcamp.vercel.app/, you can develop the ability to read code written by both AI and humans, and

You will be able to develop the ability to guide AI on how to improve code.

It includes gamification elements, so you can have fun while tracking your skill improvements.

It is free to use anytime without the need to log in.

Although there are some shortcomings and parts where the questions have not yet been filled in,

I introduce this with the hope that it will be helpful to you.

I would appreciate it if you could use it lightly.

February 10, 2026, Sincerely, Jinsu Park (Arigaram).

I've significantly enhanced the course curriculum.

So I've included almost everything needed for an introduction to the C language.

With gratitude to those who purchased this course early

We enhanced the existing lectures rather than organizing them as separate courses.

However, the lesson content that was included in the existing lectures needs to be supplemented and

I need to add the class content that has been organized as new courses

Please wait, and I will gradually fill in the content step by step.

Thank you.
