Answer 2

A pointer is a variable that stores the address of another variable. Unlike other variables that hold values of a certain type, pointer holds the address of a variable. For example, an integer variable holds (or you can say stores) an integer value, however an integer pointer holds the address of a integer variable.
Here is how we can declare pointers.

int* p;

Here, we have declared a pointer p of int type.

You can also declare pointers in these ways.

int *p1; int * p2;

Let's take another example of declaring pointers.

int* p1, p2;

Here, we have declared a pointer p1 and a normal variable p2.
