Question

The code is as following

// in ptr.h
#pragma once
#include <memory>
template<class T> using Ptr = std::unique_ptr<T>;

So every time I use std::unique_ptr, I include “ptr.h” and use it as Ptr. Is this a good practice?

Answer 1

This kind of thing only hurts readability. The odds are higher that the average C++ programmer will know what a unique_ptr is before they know what your notion of Ptr is. Moreover I can google the former and not the latter.
