Welcome to the “Advanced C Programming Masterclass: Pointers & Memory in C”! This best-seller course is designed to elevate your C programming skills, with a particular focus on the C language, topics related to embedded C, and advanced C.

Introduction

C programming language still remains one of the most popular and used languages in 2023 and has great career options in different industries, such as:

– Cyber Security.

– Smart Homes & Smart Cities.

– Drones.

– And especially in Embedded Systems.

What will you learn in this course?

There is an ‘ancient’ phrase saying “to become an expert in C – you need to master pointers”.

One of the main objectives of this course is designed to take your basic knowledge of pointers (one of the most significant topics) to the next level. The goal is to take the basic skills you’ve gained so far in C programming and take this knowledge to a whole new level.

We will cover pointers, memory addressing, pointers to functions, advanced concepts of structs and dynamic memory allocation, and so much more.

The beauty of this course is that it regularly gets updated with new material. And the material being added to the course these days includes lots of information in the low-level programming (the bits and bytes), preparation for usage of Embedded C in Embedded Systems, and other very important topics for the next generation of engineers.

This course covers the topics in-depth, from different angles, and with various visualizations and illustrations – that should make the learning process of pointers and low-level programming much easier and fun for you.

Also, you will get a whole dedicated section on how to use a debugger and what is the debugging process that may help you so much in developing your future applications.

After completing this course you will gain plenty of new skills and knowledge that may improve your chances of getting a job position as a C Developer as well as increasing your chances to pass the exam (if you’re still a student).

What’s different about this course?

Vlad Budnitski will be your instructor for this course.

He has years of experience working as a Software Developer (also working with complex systems developed in C language). As well as 4 years of experience teaching C Programming for Beginners and Advanced C Programming in College.

So you got lucky on this one because you will get knowledge from a practical software developer and experienced instructor.

You will get a handpicked, concise, and straight to the point material that you will be amazed by the way these complicated pointers can be taught.

This course is also guided with concrete exercises, challenges, and full solution videos – that will help you to practice the materials.

Who’s this course for?

First of all, this course is not for “absolute beginners” and it requires you to have at least the basic knowledge of programming. It’s assumed you have some knowledge of the basics in C – preferably having completed our “C Programming for Beginners” course (here on Udemy).

This course is great both for students in college as well as graduates who need to learn and understand pointers in depth.

In addition, if you’re planning to explore and master the Embedded Systems domain using Embedded C – then this course is a great preparation of various topics for the Embedded Domain. Once you master all the concepts of this course you’ll be a few steps closer to proceeding and mastering Embedded Systems, programming Micro Controllers, etc.

So, once again, why this course?

  1. Investment of Time: We’ve spent hundreds of hours perfecting this course to make your C language learning experience engaging and fun.

  2. Best-Seller Status: Our course stands out among others. It’s a top choice for learners due to its in-depth, easy-to-understand approach to complex C programming topics.

  3. Ease of Learning: Don’t worry about getting confused or lost. We’re experts at breaking down difficult concepts into easily digestible content.

  4. Staying Current: We keep our content fresh and relevant with constant updates and improvements. Currently, we offer over 40 hours of practical C programming content.

  5. Hands-On Training: Theory is good, but practice is better. We provide lots of exercises, complete with video solutions to help cement your knowledge.

  6. Community Support: Got questions or doubts? Our active Q&A community is here to provide answers and support your learning journey.

List of topics

Our course covers a wide variety of C programming topics including:

  • The ABCs of Pointersin C Language: From declaration, initialization, usage, to dereferencing and more

  • Unraveling Complex C Programming Concepts: Multiple indirection, pointer arithmetic, and generic pointers

  • Memory Management: Dive into dynamic memory allocation, using C functions like malloc, calloc, realloc, and free

  • Advanced C Topics: Learn about dangling pointers, using the Valgrind memory leak tool, sizeof operator, arrays, strings, and the secrets of using pointers in strings

  • Function Mastery: Grasp function pointers, arrays of pointers to functions, structs, and pointers

  • Debugging Skills: Enhance your problem-solving capabilities with debugger and debugging techniques in C

  • Further Exploration: Delve into 2D matrices with pointers, computer architecture, data and structs alignment, sequential and textual files, structural and binary files, and project management

  • Detailed Insights: Understand MACRO, Enums, Constants, Bitwise Operations (Embedded), and Bit Fields

  • And more!

Words From Our Students

Check out what our students have to say about their experience with us:

“The lecturer explains the material clearly and intelligibly. The teaching material is well developed. So far, so good!” – Andrejs Ogurcovs

“This course is amazing for embedded systems engineering. Inside of this course there are a lot of examples of curriculum also about pointers that makes it helpful for learning.Finally I have understood to pointers. I wıll use in embedded systems that i have learnt knowledge about c programming in this lecturer.Thanks for your effort Vlad. Best regards.” – Emre Çakır

“This course is AWESOME AWESOME AWESOME. I had so many courses for C, and all of them copied each other. They mention about pointers in just 1 (ONE) video (10 minutes). If you have a programming experience, start from this course. AWESOME AWESOME AWESOME. If I could have gave 1000 starts, I would do this. The examples, exercises, slides, topics, the voice of the teacher, everything is flawless” – beyza Erdoğan

“Having this opportunity to review C and Pointers is pretty awesome. I have learnt a lot from Vlad about C which could be regarded as the fundamental of almost every programming language. I have taken Vlad’s course from C Bootcamp to this advanced pointer course, and now I am confident to say that I know about C because I understand pointers now!! Hoping there would be more algorithm contents in the future, thanks Vlad!” – Matsu Chen

“Hands down this is the best course I have ever done. Visual clarification was very useful for understanding what is happening behind the scenes. I hope Vlad makes extensions of this course with more advanced topics and exercises. Thanks Vlad!” – Venelin Stoyanov

“Vlad did a great job explaining, illustrating, and covering many essential topics in pointers with enough examples. After completing this course, I feel more confident in using pointers in c programming.” – Abdel Alkuor

“I did the first course C Programming Language for Beginners and I liked it. This course is in the same level or more until now. Thank you so much.” – João Henrique Berg dos Santos

“I struggled so much understanding pointers and how they work, and why do I need them, I also struggled with the dynamic memory allocation, but after that course I think everything cleared, and even if I am still not working perfectly with these things, I finally understood them and how they work. Thank you so much Vlad! It was pleasure watching your videos!” – Julia Vasileva

“Highly recommend taking this course for any student in college. Saved me so much time and effort. It was clearly explained, straight to the point, covered in a couple of hours more than my teacher covered in the entire semester.” – Nikolay

Do you still have doubts?

That’s OK. Pointers can get us all confused to some extent… If you’re still unsure if this course is exactly what you’re looking for, feel free to go over the full detailed curriculum.

In addition, we offer a full money-back guarantee for 30 days. So, you can enroll risk-free today, and get ready to master the world of advanced C programming! We can’t wait to start this journey with you.
