Go Tutorial for Beginners: Build a CLI with Packages, Types, Slices, Maps and Errors
Start with a module and finish with a working student-report command. Trace Asha's scores through slices, a map and a struct, then test three useful failures.
Arrays in C++: Sequential Storage, Indexing and Worked Examples
Build one C++ array from declaration to traversal, updates, memory addresses, fixed-capacity insertion and deletion, then extend the model to two dimensions.
Classes and Objects in C++: Beginner Tutorial with Runnable Examples
