I understand pointers and know what they are and how to declare them. But, the problem is, none of the books, tutorials or guides actually explain why pointers are used.
I come from a PHP background, where pointers are not used. So when I declare a string, I don’t use a pointer.
I see pointers being used in header files when creating methods, and I really don’t understand why they are there for.
Any help would be appreciated.
