Pointer is a special variable in which the value stored are the addresses of some other variable(or function also in some cases)
int *a;

The statement written above means that a is a special variable(i.e. pointer) that will store an address of another variable which is integer.
For eg.


int *a;
int b=10;
a=&b;

then it will be like this-



Here 3465 is address for variable a and 1217 is address for variable b.


NOTE:All variables store integers bcoz address are always integers....
thus if we write

char *a;

It will not mean that a will store character it means that it will store the address of some variable whose datatype is char.
