C++ Basics: Moving Resources

In C++ we have move semantics which is a way to move resources to avoid making copies in the memory which not only will make our program slower but also use more space than necessary.

Introduction — Why Moving Resources

When writing a program you will encounter a case where you need to move (large) resources around from one object to another.

In C++ we have move semantics which is a way to move resources to avoid making copies in the memory which not only will make our program slower but also use more space than necessary.

We are not discussing the Move Semantics here, because there are a lot of resources you can find on the internet explaining rvalues and Move Semantics.

What is not so obvious is that when we can rely on the compiler to help us move our resources around, and when we have to write our own move constructor and move assignment operator.

This article will introduce the concepts and topics common to all programming languages, that beginners and experts must know!

Although we still talk about programming as a standalone career, the dominance of technology in our lives makes it clear that coding is much more than a career path. In my opinion, computer science is more than a college major or a high-paid job; it’s a skill, essential for thriving in a modern-day economy. Whether you work in healthcare, marketing, business, or other fields, you will see more coding and have to deal with a growing number of technologies throughout your entire life.

When do we need to write our own move constructor in c++? This article answers this basic question which is often very confusing for beginners.
