Postfix opreator =variable & operator.

Prefix opreator =operator & variable.

eg : a=42;

       b=a++;

postfix operator form is a++ i.e, b=a then a=a+1;

prefix operator form is ++a i.e, a=a+1 then b=a;

Postfix - Use & Operate ( Ex : a++ )

Prefix - Operate & Use ( Ex : ++a )

For Example,

Assume a=1 and

if b=a++ then b=1

if b=++a then b=2

value of b =1

value of c= 3
