A large number of student responses to questions on a

multiple-choice examination are to be processed by a

program that you will write.

The input to your program will consist of

the correct answers to the exam questions

the actual student responses (assume that there can be no

more than 500 students).

The responses //sample file provided to use (called

exams.dat) (blank spaces are unanswered question)

ABDEBBAC D

ABCE CACED

DCE AEDC

ABCEB ACED

BBCEDBACED

DBCE CACED

ABCE CA E

BBE CACED

CBCEDBACED

Note that for every exam question there are precisely 6

possible answers: A, B, C, D, E and blank.

The last case is to allow the possibility of a student not

responding at all to a question.

Since the student answers are to be read in from a file,

you should “echo” the data on to the computer display

screen as it is being read.

The output from your program will consist of

a complete listing of the students\' scores (the number of

correct answers, incorrect answers, and blank answers);

these may be given by student number (as illustrated

below).

a second listing, like the one shown below, which

illustrates how the group as a whole answered each

question on the examination.

Here is how the output from your program should appear

when executed:
