What are const pointers in C++?
Const pointers in C++ are pointers that cannot change the address they point to after initialization.
Can you give me an example of how to use a const pointer?
Sure! Here's an example:
int value = 10;
int* const ptr = &value; // ptr is a const pointer to an int
*ptr = 20; // This is allowed, changing the value at the address
// ptr = &anotherValue; // This would cause an error, as ptr cannot point to another address.
What happens if I try to change the pointer's address?
If you try to change the address of a const pointer, the compiler will throw an error, as const pointers are meant to maintain a fixed address.
Are there any differences between const pointers and pointer to const?
Yes! A const pointer cannot change the address it points to, while a pointer to const cannot change the value at the address it points to.
