C++ code samples belonging to Sams Teach Yourself C++ In One Hour a Day, Ninth Edition by Siddhartha Rao. The nearly 300 code samples contained in here are analyzed in detail in the book. Learn C++20 concepts, ranges, views, adaptors, modules, and spaceship <=> operator to mention a few.

File names follow this pattern: <Lesson#>.<CodeSample#> .cpp

Therefore, "1.1 Hello World.cpp" is explained in Lesson 1 and is the first sample within.
