C++ for Beginners

Compile a first program, learn the syntax and types it uses, then make decisions, repeat work, and keep many values together.

Move repeated work into functions, pass data by reference instead of copying it, and use vector, string, and algorithms from the standard library.

Group state with the functions that act on it, keep objects valid from construction to destruction, and expose only what callers should change.

Derive one type from another, make operators read like the built-in ones, and write templates that serve several types.

Report failures with exceptions, look values up in maps and sets, swap loops for standard algorithms, and let a smart pointer own heap memory while you read and write files.
