// Given the following declarations, write functions
// to do the following tasks:
//
// 1. If the string in mammal is greater than 
//    "Opossum" lexicographically, increment
//    counter greaterOpossum;
// 2. If the string in mammal is less than or
//    equal to "Jackal", decrement counter
//    lessEqJackal.
//
// The animal names will be read in from file
// "mammals.txt".
//
// Hint: use strcmp to do the comparison. Depending
//       on the return value of strcmp (<, =, or > 0),
//       determine each string comes first in the
//		 lexicographic order.
