Description
Purpose:
* Demonstrate (elementary) understanding of how to write,
compile, and run a program in three useful languages, C ,
Java, and Python.
———————————————————————-
Background:
* Just three “Hello, world!” programs to ensure that you have a
working environment for the languages C , Java, and Python 3.
———————————————————————-
Tasks:
1. Download HMWK_01_dalioba.zip from Blackboard.
2. Unzip the file somewhere convenient.
3. Change ‘dalioba’ in the name of the directory to your NetID.
(Your NetID is three letters followed by four or five digits.
The directory name will now be something like
‘hmwk_01_abc1234’, where ‘abc1234’ is YOUR NetID.)
4. Look in that directory.
5. Change the header lines in the files hmwk_01.cs / .java / .py.
— Line 1: Family name first, then a comma, then
personal name.
— Line 2: Your NetID.
— Line 3: The date you edited the file.
6. Change line 11 in the hmwk_01.cs file to be whatever is
necessary to print “Hello, world!” when this C program is
compiled and run.
7. Change line 8 in the hmwk_01.java file to be whatever is
necessary to print “Hello, world!” when this Java program is
compiled and run.
8. Change line 6 in the hmwk_01.py file to be whatever is
necessary to print “Hello, world!” when this Python program
is run. Ensure that you use Python 3 (THREE!) syntax and not
Python 2.

Submission:
Make a zipfile of your ‘hmwk_01_abc1234’ directory (with your
source files in it) and submit it on Blackboard as your results
for this assignment. REMEMBER: ‘abc1234’ should be replaced with
YOUR NetID.
Your submission will be run and you will score 1 point for a
running program and 1 point for the correct output.
Therefore, the maximum possible score for this homework assignment
is 6 points (2 + 2 + 2).
You can get dinged points for work not in the proper format so
even if your programs work (and work correctly!), you might not
earn full credit. Check your work!
———————————————————————-
Hints:
1. Ensure your programs compile and run correctly. Not
compiling or not generating the correct output
(“Hello, world!”) will cost you points. Compare your program
output to that shown in the screen shots. Match it EXACTLY.
(‘EXACTLY’ means absolutely character-by-character the same:
those thirteen characters then a newline.)
2. Ensure that you update the three header lines in each of the
source files with YOUR name (family name first, then a comma,
then your personal name), YOUR NetID, and the date you edit
the file.
Not updating the header lines properly will cost you points.
3. Ensure that you use Python 3 (THREE!) and not Python 2.
There are differences between Python 2 and 3 that will affect
even this simple program. If your Python program does not
run properly using Python 3 you will get ZERO points for it.
4. Ensure your submission is packaged EXACTLY as described above.
— Your submission should be a ZIP FILE (not a tar, rar, gz,
or any other kind of compressed file).
— The zip file should be named ‘hmwk_01_abc1234.zip’ (with
‘abc1234’ replaced with YOUR NetID).
— This zip file should have ONE item in it, a directory
named ‘hmwk_01_abc1234’ (with ‘abc1234’ replaced with
YOUR NetID).
— Your source files should be in that directory. The
source files should be named hmwk_01.cs / .java / .py.
Submissions in the wrong format score ZERO points.
5. After you submit your zip file on Blackboard, download it
from Blackboard and check that your submission is in the
proper format, that the programs run and print the correct
string, and that you updated the header lines correctly in
each of the source files.
6. Are you CERTAIN you complied with all of these nit-picking
instructions? Really? Maybe you ought to check just one
more time. 🙂
