 This *open-access* course is directed at those who are already familiar with C and object-oriented programming towards a proficiency level of C++ programming. The course covers the basics of C++ programming and moves on to advanced C++ semantics and concepts.
 
 **Key features**:
 
 - *Free and frequently updated*
-- *22 lectures, ~1500 slides*
+- *26 lectures, 1800+ slides*
 - Include the *last language standard* concepts and features
 - *Practical teaching*: non-verbose, short structured descriptions associated with code
 - *Minimal code examples* for showing just a specific feature or issue without digressing
 - *Complementary language aspects*: tools, coding conventions, project organization, and code optimization
 - *Experience-based*: many aspects, examples, and problems come from real-world cases faced during my work as software engineer
