+
+1. struct cannot be put inside of main(). 
+2. Structures are collections of related variables under a single name. Enumerates define a set of named integer canstants starting from 0. 
+3. Passing an array directly to a function as an argument. Passing a structure containing an array causes the array to be copied to the function's parameter.
