In Fig. 3.18 we see a sketch of getRelop(), a C++ function whose job is to simulate the transition diagram of Fig. 3.13 and return an object of type TOKEN, that is, a pair consisting of the token name (which must be relopin this case) and an attribute value (the code for one of the six comparison operators in this case). getRelop() first creates a new object retToken and initializes its first component to RELOP, the symbolic code for tokenrelop.
