C++ Smart Pointers for Resource Management
Use unique_ptr to express exclusive ownership; it is automatically released when the scope ends.

1#include <memory>2#include <iostream>34class Buffer {5public:6 Buffer(standard::size_t size) : data_(new character[size]) {}7 ~Buffer() { delete[] data_; }8private:9 character* data_;10};1112int main() {13 auto buffer = standard::make_unique<Buffer>(1024);14 standard::cout << allocated << standard::end;15 return 0;16}Key Points
- make_unique avoids manual new and prevents memory leaks on exceptions.
- Do not construct multiple smart pointers from the same raw pointer.
Usage suggestions
Run the copied code in a local sample project first to verify expected behavior, then adapt the naming and structure to your business needs. Pasting directly into a large project can cause you to overlook contextual differences.
