Const Propagation for Pointers
Explore how to enforce const-correctness in C++ by learning const propagation for pointers. Understand the common pitfalls of mutating pointer targets in const objects and how to use std::experimental::propagate_const to prevent such mutations. This lesson helps you write safer, more maintainable code by ensuring immutability is properly propagated through pointer-like objects.

Propagation pointers
By using the keyword const, we can inform the compiler about which objects are immutable. The compiler can then check that we don't try to mutate objects that aren't intended to be changed. In other words, the compiler checks our code for const-correctness. A common mistake when writing const ...
