Problem 1 (30 points):  

A.  Write a function called biggest_index which takes an array 
of integers and the size of the array as parameters.  The function
should return the index position of the biggest integer in the array.

B.  Write a program which asks how many cookies the user has eaten
each day for a year (365 days).  The program then prints how many
cookies the user ate on the day following the day the most cookies
were eaten.  If the most cookies were eaten on the last day of the
year, then just print a message saying that the most cookies were
eaten on the last day of the year.  [Use the function from part A.]

Problem 2 (40 points):  

A.  Write a function called at_least_one which takes two characters 
and a string as parameters.  The function should return true if at
least one of the two characters appears in the string, otherwise false.  
For example, if the two characters are 'n' and 't', then the function
will return true for the string "angel", and also for the string "sweet"
and the string "innocent".

B.  Write a function called ef_file which takes an input file stream
as parameter.  Assume that the input file stream is already associated
with a file that has been opened.  (Assume the file contains only words
made up of lower case letters with no numbers or punctuation.)  The
function should return true if every word in the file contains an 'e'
or an 'f', otherwise false.  [Use the function from part A.]  For 
example, the function will return true for the following file:

                 ************************************************
                 * the greedy student ate the loaf of french    *
                 * bread while the evil baker baked three more  *
                 * loaves of bread                              *
                 ************************************************

Problem 3 (30 points):  

A.  Define a class called person with private data fields for first
name, last name and test_grade, plus a prototype for the public member
function in part B of this question.

B.  Write a member function for person called pass which returns true if 
the person passed the test (at least 60), otherwise false.

C.  Write a nonmember function called both_pass which takes two persons
as parameters and returns true if both of the persons passed the test, 
otherwise false.
