C++ learning tracks

Get started with C++ exercises. Learn how compilation, tests and clang-tidy checks work, and use their feedback to revise your code.

Work with initialization, integer types, conversions and auto deduction. Recognize narrowing and signedness issues before they produce incorrect results.

Manage resources through object lifetimes. Use constructors and destructors to make cleanup predictable, including when control leaves a scope early.

Understand copying, moving and the rule of zero. Track ownership and operation costs, and let member types manage resources where possible.

Distinguish owning objects from borrowed references and pointers. Choose interfaces that communicate access and keep borrowed data valid.

Use standard containers, strings and algorithms. Reason about growth, lookup costs and reference invalidation when choosing and modifying collections.

Design class interfaces with const-qualified operations and deliberate constructors. Control implicit conversions and make allowed operations clear to callers.

Handle failures with return values, exceptions and explicit termination policies. Read the guarantees of an operation and choose an appropriate response.
