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

We’ll meet developers who don’t think `const` is helpful and who argue against this practice. We’ve learned about their arguments and how to respond to them:

* `const` is not visual noise because it doesn’t repeat information
* `const` is not confusing if used correctly, and we can use it even if it has not been used in the codebase before 
* `const` will not harm performance, and in fact can help the compiler to optimize results if it is used correctly
