Answer 2

What is a variable?
A variable is a piece of memory that stores a value (numbers or strings).
for example -
int a = 5 // a is variable.

now
What is a pointer?
A pointer is address of the memory (in RAM) where variable is saved.

An example -
int a = 5 ;
cout<< a ; //prints 5
cout << &a ; //prints address of variable a.

here & operator is called reference operators.
