What are the limitations of const pointers in C++?

Const pointers in C++ cannot be reassigned to point to a different address after initialization, but the data they point to can be modified if it's not a const data type.

Can you give me an example of a const pointer?

Sure! Here's an example: int a = 10; int* const ptr = &a; Here, ptr is a const pointer to a, meaning you can't change ptr to point to another variable.

What happens if I try to change the pointer?

If you try to change a const pointer, like ptr = &b;, the compiler will throw an error because ptr is declared as a const pointer.

Are there any scenarios where const pointers are useful?

Yes, const pointers are useful when you want to ensure that the pointer itself cannot be changed, providing safety in functions that modify data without altering the pointer's address.
