Postfix Operators 

Postfix operators are unary operators that attach to the end of postfix
expressions.  A postfix expression is any expression that may be legally
followed by a postfix operator.

Syntax 

     postfix-expression ::=
            primary-expression 
            postfix-expression [ expression ]
            postfix-expression ( [argument-expression-list] )
            postfix-expression . identifier 
            postfix-expression -> identifier 
            postfix-expression ++
            postfix-expression --

     argument-expression-list ::=
            assignment-expression 
            argument-expression-list , assignment-expression 

Examples 

The following are examples of postfix operators:

     The 'element of' operator ([ ])     : array1[10]

     The postfix increment operator (++) : index++

     The postfix decrement operator (--) : index--

     The argument list of function calls : func(arg1,arg2,arg3)

     The selection operator (.)          : struct_name.member

     The selection operator (->)         : p_struct->member
