C++: Const vs Non-Const Pointers

What is the difference between const and non-const pointers in C++?

In C++, a const pointer means that the pointer itself cannot change the address it points to, while a non-const pointer can.

Can you give me an example of how to use a const pointer?

Sure! Here's an example: const int* ptr = &value; This means ptr points to an integer that cannot be modified through ptr.

What happens if I try to change the value of a const pointer?

If you try to change the value of a const pointer, you'll get a compilation error because the pointer is declared as const.

Are there any scenarios where I should use const pointers?

Yes, use const pointers when you want to ensure that the data being pointed to cannot be modified, which helps prevent accidental changes.
