C++: From First Program to Expert Craft

Start by compiling your first program and progress to safe, concurrent and efficient modern C++, using C++20 as the baseline and calling out compiler and standard-library support.

Start with “From Source Text to a Running Program”15 modules · 104 lessons ready

This track teaches modern C++ the way the machine runs it. Every lesson opens with a step-by-step trace of memory, objects or the build pipeline, so you see what a line of code does before you learn the rule behind it. You move from compiling a first program, through classes and the standard library, to templates, concurrency and performance. C++20 is the baseline; version-specific library extensions are labeled by standard, and draft features are not presented as released standard facilities.
