A pointer is a variable that stores a memory address. Pointers are used to store the addresses of other variables or memory items. Pointers are very useful for another type of parameter passing, usually referred to as Pass By Address.

Answer 2

In programming, a variable that stores the address value of another variable is called a pointer. The variable can be of data type integer, char, functions, array, or maybe other pointer variables.

Explanation:

In the given image, the pointer variable is containing the address of the int type variable ff4. Whereas the variable has a numeric value of 60. But the address of this pointer variable x is aa9.

An indirection operator(*) is used to print the value of a pointer variable.
