AI overview
A pointer is a type of data in computer programs that stores the address of where information is kept in the computer's memory, rather than storing the information itself. Pointers matter because they allow programmers to efficiently access and manipulate data by referencing its location, and they're essential for features like dynamic memory management and creating complex data structures.
