In Listing 4.3, fptr is the function pointer data type. To invoke the crossover routine

now is as simple as passing the case index to the array of function pointers to point

to the right function. One disadvantage of using this is that the order of the function

pointers is critical, and it has to be in exactly the same order as in the definition of

the enumeration data type. Otherwise, a different function will be called. Cautions

thus have to be taken when deleting and/or adding cases.

Handling memory is always a challenge ...
