Which regarding a pointer variable is true?

A pointer variable, also referred to as a pointer or just a pointer, functions similarly to other variables that can hold data. A pointer saves a memory address instead of a value like a conventional variable would (such as an int, double, or char). Similar to a regular variable, pointers must be declared before they may be utilized.

Why not use variables instead of pointers?

In essence, a pointer can be used to point to any variable of the same type (e.g. any integer, double, char, etc.).

                            The values of numerous distinct variables of the same type can be updated or changed using this method. Using pointers speeds up execution as well. More quickly can be accessed memory.
