LearnCpp

Start with chapter zero if you have never configured a compiler. The early lessons explain the toolchain before moving into variables and program structure, so setup is part of the learning rather than an assumed skill. Later topics make the site useful for revisiting details. Expect to read and work through code in your own development environment. No prior programming experience is required. The contents include compiler settings and choosing a C++ language standard, so check those lessons against the compiler you install.
