Teaching/Testing.
Write a program that
gives a
multiple-choice test,
for example, a voca-
bulary test.
Include ten questions. The program should write the student's name
and
all
ten responses
onto
a cassette data
file.
Design the program so
that any number of
students
may
take the test in
sequence. Include
instructions about
when
to
use the RECORD,
PLAY and
STOP keys.
Write
a
grader
program
that uses the data
file created above to
read each student's
name
and
responses,
grade the
test, and then read
the
next student's
test.
Be sure to
leave
time for the
teacher to
mark
down
the
names and grades in his or
her little black book.
