# modernize-make-shared

This check finds the creation of `std::shared_ptr` objects by explicitly calling the constructor and a `new` expression, and replaces it with a call to `std::make_shared`.

    auto my_ptr = std::shared_ptr<MyPair>(new MyPair(1, 2));

    // becomes

    auto my_ptr = std::make_shared<MyPair>(1, 2);

This check also finds calls to `std::shared_ptr::reset()` with a `new` expression, and replaces it with a call to `std::make_shared`.

    my_ptr.reset(new MyPair(1, 2));

    // becomes

    my_ptr = std::make_shared<MyPair>(1, 2);
