This is a closed-book, closed-notes examination.  There are six
problems, each worth 16 points.  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 each of the problems, you need to write a program or
a function.  You do not need to write comments.  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 1:  Write a function called sum10 that has two 
integer parameters and returns true if the sum of the two
numbers is larger than 10.  Otherwise it returns false
------------------------------------------------------------------------------
Problem 2:  Write a function called make0 that has two
integer parameters.  The function should set the 
smallest of the integer parameters to 0.
------------------------------------------------------------------------------
Problem 3:  Write a function called diff that has two
integer parameters, and returns the difference of the first
input minus the second input if that difference is positive.
Otherwise it returns 0.
------------------------------------------------------------------------------
Problem 4:  Using the above functions, write a program that
reads in two numbers.  The program should print the difference
of the two numbers if the difference is positive.  Then the program
should print a message saying whether the sum of the two numbers is
larger than 10.  Finally the program should set the smaller of
the numbers to 0 and then print the numbers.
------------------------------------------------------------------------------
Problem 5:  

A.  Write a function called smallest to read doubles until zero is 
    read in and return the smallest of the doubles read in, 
    except for zero.

B.  Using the function in part A, write a program to read in double
    until zero is read in and print out the smallest float read,
    except for zero.
------------------------------------------------------------------------------
Problem 6:

A.  Write a function called count10 to read integers until a 
    negative is read in and return the number of integers
    smaller than 10 that were read in (excluding the negative).

B.  Using the function in part A, write a program to read in 
    integers until a negative is read in and print out the 
    number of itegers read in smaller than 10 (excluding the
    negative).
