Part I    --  Choose the best answer   (each question is worth 2 points)

1.        Pascal is a high level language ( T / F ).

 

2.        A directory can contain only files in it ( T /  F ).

 

3.        A program must be stored in main memory while being executed by the computer ( T / F ).

5.        Assume that the only files in the current directory are
      progm1.pas, progrm1.pas, progm2.pas and program.pas.
What command will ONLY remove the files progm1.pas and progm2.pas ?

(i.e. program.pas and progrm1.pas will not be removed, but the other two files will be)

  1. remove pr*.pas

Part 2

 

                c:\                                                                                                       a:\

 


JOHN              CASEY                                                          INVENTORY                         PAYROLL

 


CP610         CFILES           PAS_FILES                                                               STUDENTS           FACULTY

 

                hello.c              average.pas          data.txt                                                                   pete.txt          jim.txt

 

 

NOTE:   JOHN, CASEY, CP610, CFILES, PAS_FILES, INVENTORY, PAYROLL, STUDENTS,                                         

                FACULTY are directories.

                hello.c, average.pas, data.txt, pete.txt, jim.txt are files.

 

 

1. (1 point) Give the full path name of average.pas:   _________________________________________

 

 

2. Suppose the current directory is PAYROLL:

a.        (2 points) What is the output to the screen when the command dir a: is issued ?

 

 

 

 

 

 

b.       (2 points) Write a command to create a subdirectory STAFF under PAYROLL: ________________

 

 

 

3. (2 points) The current directory is PAYROLL.

    Write a command to copy the file pete.txt to the directory CFILES in drive c:

 

 

 

 

4. The current directory is PAS_FILES.

    a. (2 points) Write a command to change to the directory CFILES:   __________________________

 

 

    b. (2 points) After the command in 4a is executed, write a command to change the name of the file

        hello.c to greeting.c.

 

 

 

 

5. The current directory is PAYROLL.

    a. (2 points) Write a command to change the current directory to its parent directory (note that the

        parent directory of PAYROLL is the root directory of a: )

 

 

 

c.        (2 points ) After the command in 5a is executed, write a command to remove the directory

INVENTORY.

 

PART 3 – This part requires that you use the computer  ( each question is worth 2.5 points)

 

NOTE: When you are asked to list menu items that you selected, give both the menu name and the name of the item in that menu. For example,  "File  |   Save"

 

PROGRAM SquareRoot;

VAR

     value            : integer;

     square_root  : real;

 

BEGIN

   write('Enter an integer and I will compute its square root: ');

   readln(value);

   square_root := sqrt(value);

   writeln('The square root of   ', value, '  is:   ', square_root:5:3);

END.

 

1.        (2.5 points) Enter the Turbo Pascal environment and list all the steps you went through (i.e. what menu items did you click on, what keys did you press, etc).

 

 

 

 

 

2.        (2.5 points) Type in the above program and save it to the current drive under the name "First.pas".

List all the commands you used (again menu items and/or keys pressed).

 

 

 

 

 

 

3.        (2.5 points) Compile the program and run it on the input data your TA assigned. Write the output of the program.

 

 

 

 

4.        (1.5 points) What error do you get if you change the type of the variable square_root to integer instead of real (write the error message).

 

 

 

(1 point) What is this type of error called: syntax error  or  run time error ?

 

 

5.        (1.5 points) Run the above program on input:  -4  Write the error message you get:

 

 

(1 point) What is this type of error called: syntax error  or  run time error ?

 

 

6.        (2.5 points) Exit Turbo Pascal and logoff your account. List all the steps that you went through.
