/* Project 71
   Structs - Based on this Book: Beginning C - From Novice to Professional (Ivor Horton)
   pg. 414 - Using Arrays of Structures 
   
   This program shows how to use structured structs; on each iteration the user is
   prompted to indicate if he or she wants to enter data for another horse by entering Y or N.
   Note that the printf() statement uses a conditional operator to insert "nother" into the 
   output on every iteration after the first:)
   
   Some notes:
   hcount - used to accumulate the total number of structure entered;
   scanf() - Reads the char/int entered by the user; 
   break - immediately exits from the loop if the response is negative;
   struct horse My_horses[50] - This creates the potential for the program to read in data for up to 50 horses
