Custom Implementation of make_unique in C 11
make_unique is a utility function introduced in C 14 to create a unique_ptr object with a dynamically allocated instance. This is useful when a raw pointer is not desired and ownership management is necessary. However, if your compiler does not support make_unique, it can be easily implemented using a custom template function.
To write make_unique, the following template declaration is used:
<code class="cpp">template< class T, class... Args > unique_ptr<T> make_unique( Args&&... args );</code>
This template takes a type T and a variable number of arguments Args. The following implementation creates a unique_ptr object with a new T instance constructed using the provided arguments:
<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>
The std::forward
This custom implementation of make_unique mimics the behavior of the standard version, allowing you to create unique_ptr objects in C 11 environments where make_unique is not supported.
