If that token is an operator, eval calls itself to parse more of the string and eventually obtain the values of the two operands, then applies the operator on them and returns the computed value. On most RPN calculators this is called the "Enter" key and fulfills a similar function to an equals key on a conventional calculator but in reverse. 7. Reverse Polish notation (RPN), also known as Polish postfix notation or simply postfix notation, is a mathematical notation in which operators follow their operands, in contrast to Polish notation (PN), in which operators precede their operands. In this program, we call longjmp to signal a syntax error in the input expression, such as a missing or incorrect token (in eval) or extra non-blank characters (in main). For example, we could have introduced an array of indices to tell us where the tokens start within the string. A longjmp referring to the same value ensures jumping to the point after setjmp's returning. The stack now contains just the number 8. What does "ima" mean in "ima sue the s*** out of em"? 9.
