/* Horse race simulation
The program runs as is but:
line 76 needs to find if anything other than a number was entered.
then add to line 81. If a letter is entered the program goes into
an infinite loop (scrolls). use "isdigit" ?? if so, how?
line 132. If the 3 selected horses show up IN ANY ORDER this line will result in
"win" being displayed. This is wrong. How to rewrite it so that in order to
win: the "v" number must come in first, the "w" number must come in second
and the "x" number must come in third? Have tried and tried and tried to make
this work right! :(
Since all three drawn numbers will have a "1" in it's element how do you know
which is which? How can you evaluate if the relationship is equal between v &
win, w & place, x and show?*/
