C++ 是一门拥有众多特性的语言，根据你想学习的特性，有不同的迷你项目可以练手：

• RAII and move semantics - implement unique_ptr

• Operator overloading - implement complex

• Raw arrays and pointers - implement vector

• Memory management and introdue to atomics - implement shared_ptr and weak_ptr

• Unions and pointers and c-style strings - implement string with small string optimization

• Bit operations - implement bitset

• Memory allocation strategies - implement allocator

• Template metaprogramming - implement tuple

• Algorithms - implement sort

• Multithreading, concurrency, locks, condition variables - implement future and async

• Exceptions - discuss the various exception safety guarantees and how to fulfill them when implementing the above features.

• Cache friendly structures - use/measure std::map and std::unordered_map. Implement map as a sorted array. Implement unordered_map using various hashing strategies - measure performance and discuss tradeoffs.

而综合性的项目，则需要根据你的兴趣或需求进行选择了。
