Modern C++ for Fun and Profit: This isn’t your old C++
summary
C++11/14/17 features get concrete treatment: auto, range-based loops and Eric Niebler’s ranges for lazy pipelines, lambdas that deduce with auto, move semantics enabling cheap return-by-value and move-only types, unique_ptr/shared_ptr and make_shared optimization, constexpr that folds work into compilation, and fold-expressions for variadic checks. Examples: found dozens of printf misuse sites using a compile-time type check; -fdump-tree to inspect GCC optimizations and confirm loop unrolling; constexpr pow moved work to compile time, showing real speedups and cross-compiler (GCC/Clang/MSVC) readiness.
