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

For reference types, adding the `const` qualifier creates another overload. This behavior is great because it ensures the variable we pass remains unmodified. If `const` was ignored here, the variable could be changed and could cause many issues down the line.  However, that is not the case.

## Reference type parameters
For reference type parameters, the `const` qualifier is not ignored.
