This is a closed-book, closed-notes examination.  There are four
problems.  Do not spend too much time on any problem. Read them 
all through first and solve them in the order that allows you to 
make the most progress.  

For all of the problems you need to write a program.
You do not need to write comments, include statements,
or meaningful variable names.  Assume that the type bool
exists.  You don't need any error checking.  When you ask 
the user for information, just write something short.  
Your program doesn't have to be fancy or user-friendly.  
You should make it as simple as possible, as long as it does 
what is required.

Problem 4 

A.  Write a function called weight_drop which takes an array
of integers and the size of the array as parameters.  The 
array values indicate your weight on given days.  Assume you 
began a diet on a certain day.  Then position 0 of the array
is your weight on the day you began the diet, position 1 of 
the array is your weight one day after you began the diet, 
position 2 of the array is your weight two days after you 
began the diet, etc.

Your function weight_drop should return the first day that 
your weight dropped after you began the diet.  If your weight 
never dropped then the function should return -1.

B.  Using the function from part A, write a function called
diet14 that takes an array and the size of the array as
parameters.  The function should return true if your weight
dropped within 14 days after beginning the diet, otherwise
false.
