C++ std::make_unique instead of new delete

April 30, 2024

C++ std::make_unique() is a C++14 feature that creates std::unique_ptr without using new and delete. std::make_unique() is a safer and more convenient way to manage memory in C++.

GCC 4.9 circa 2014 added support for std::make_unique(), along with virtually all modern C++ compilers for several years already.

__cpp_lib_make_unique feature test macro can fence non-essential code if supporting ancient compilers is required.
