CSci 1101 Lab on loops

Reminder about sftp

This is just a reminder of basic sftp commands.

Open a terminal window. If the files that you are editing are in a directory other than your home directory, use cd command to switch to this directory.
Type sftp rynite at the command prompt, type in your password when asked
Type cd public_html to get to your public_html directory. If you want to get to a subdirectory of public_html, say, lab3, you can type in cd public_html/lab instead. To create a new directory, type mkdir lab (or any name you want to give to the new directory), followed by cd lab to get into the new directory.
To upload a file to rynite, type in put filename (where you replace filename by the actual file name).
To download a file from rynite, type get filename

Note that the files are moved between your current directory on the lab machine to the current directory on rynite. Some commands that will help you orient yourself and move around in sftp, both on rynite and on the lab machine:

pwd	shows your current directory on rynite
lpwd	shows your current directory on the lab machine
cd	changes your current directory on rynite (`cd ..` brings you one level up)
lcd	changes your current directory on the lab machine (`lcd ..` brings you one level up)
ls	shows your files in the current directory on rynite
lls	shows your files in the current directory on the lab machine
quit or exit	exits sftp

For more commands type ? at the sftp prompt.

Alternating colors

Write a program with a loop that generates a table with one row of square cells with no text (set the width and height of the cells as an inline style). Set the background of the cells to alternate between two colors. The number of cells is a variable in your program. Hint: to determine the cell color, use on if/else statement inside the loop to check if the loop counter is odd or even.

To submit

Just upload the two files to rynite AND send me an e-mail with the file names and locations.
