This is a closed-book, closed-notes examination.  There are six
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 most of the problems, you need to write a program or
a function.  You do not need to write comments or include 
statements.  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.
	
In each problem, once you have written a function in one
part of the problem, you may use the function in another
part of the problem.
------------------------------------------------------------------------------
Problem 1 (10 points):  

Write a program to read in 100 integers, then print out all
the positive numbers it read in, and after that print out all 
the negative numbers it read in.
------------------------------------------------------------------------------
Problem 2 (15 points):  

Write a function called count_t, that takes an input stream 
as input parameter.  Assume that the input stream is already 
associated with a file containing words (with no punctuation, 
capital letters or numbers).  The function should return the 
number of words in the file that begin with the letter t.
------------------------------------------------------------------------------
Problem 3 (35 points):  

A.  Write a class called person, with data fields fname, lname 
and year_born, whose values will be the first and last name of 
a person and the year that person was born.  Look at the other
parts of this question to see what else the class should contain.

B.  Write a member function called age, for person, which takes 
the current year as input parameter, and returns the age of the 
person at the end of the current year.

D.  Write a member function called match, for person, which
takes a first name and a last name as input parameters, and returns 
true if the person has that first and last name, false if not.
