Rust uses the Result type for error handling, encouraging explicit error checking and propagation. Conversely, C++ traditionally usesexceptions, which can result in performance overhead and potential resource leaks if not properly handled. Modern C++ also introducesstd::optionalandstd::expected, allowing...

The memory allocator finds an empty spot in the heap that is big enough, mark it as being in use, and returns a pointer, which is the address of that location.内存分配器会找到一块未被使用的、足够的内存区域,将其标记为使用中,并返回指针(这块内存区域的内存地址)。This process is called ...
