modern-cpp-mastery-lib

A header-only C++17 library demonstrating modern C++ features — custom containers, allocators, RAII, and move semantics.

Built as a learning project to practice the exact skills used in systems/embedded C++ roles.

---

Features

• FixedVector<T, N> — Stack-allocated fixed-capacity vector with full move semantics and range-for support
• CustomAllocator<T> — STL-compatible custom allocator demonstrating low-level memory control
• ScopedTimer — RAII-based high-resolution timer; prints elapsed time automatically on scope exit

Concepts Demonstrated

Concept	Where
Templates (template<T, N>)	FixedVector
Move semantics + noexcept	FixedVector move ctor/assignment
RAII	ScopedTimer, std::array
Rule of 5	FixedVector
Custom allocators	CustomAllocator
Iterator protocol	FixedVector::begin()/end()

Build

mkdir -p build && cd build
cmake .. -DCMAKE_BUILD_TYPE=Release
cmake --build . --config Release
./demo

Requires: CMake 3.16+, C++17-compatible compiler (clang++ / g++)

Memory Safety

Built with AddressSanitizer + UBSan:

cmake .. -DCMAKE_BUILD_TYPE=Debug
cmake --build .
./demo   # runs clean — 0 leaks
