Implementing the make_unique Function in C 11
In C 11, the make_unique function is used to create unique_ptr objects. It provides a convenient way to allocate memory and manage the lifetime of objects. For those whose compilers do not support the make_unique function, a custom implementation can be created.
To write the make_unique function, we can use the unique_ptr constructor that takes a raw pointer as an argument. The following template code shows how to implement the make_unique function:
<code class="cpp">template<typename T, typename... Args> std::unique_ptr<T> make_unique(Args&&... args) { return std::unique_ptr<T>(new T(std::forward<Args>(args)...)); }</code>
This implementation uses std::forward to pass the arguments to the T constructor, ensuring that perfect forwarding is preserved.
For compilers that support it, a more sophisticated implementation can be found in sasha.sochka's answer, which also supports the creation of unique_ptr objects from arrays. However, if sasha.sochka's solution does not compile with your compiler, the above implementation should work effectively.
