Gain insights into the C++ keyword 'const,' its usage in various contexts, and implications when returning pointers and references. Learn about preventing accidental data changes.

How to use const in C++ by Sándor Dargo_468 x 60 copy.png

In this course, you will learn about the C++ keyword const and its behaviour under different usage conditions, including local, global and static contexts. This course will help you to understand const and its implications when you attempt to return pointers and references in C++. By the end of the course, you will have a solid grip on const and its usage in preventing any accidental change of data.

Secure Coding Practices in C++: A Deep Dive into const

## What are binding rules?
The canonical signatures of the move assignment operator and the move constructor use non-`const` rvalue references.

But that doesn’t mean that `const T&&` doesn’t exist. It does, and it’s syntactically valid.

The `const T&&` is not simply syntactically valid, but the language has clear, well-defined binding rules for it.

For our binding examples, we'll use the following four overloads of a simple function `f`.
