Your password will not appear on the screen as you enter it in order to keep your password secure from others. The screen will look similar to this: <P> <TT><FONT SIZE=3 FACE="courier New">unix(r) system V Release 4.0 (bsu-cs) </FONT></TT> <P> <TT><FONT SIZE=3 FACE="Courier New">lo~in: your_login_name<return></FONT></TT> <BR><TT><FONT SIZE=3 FACE="Courier New >password: your_password<return> </FONT></TT> <P> Once you have entered your login name and password correctly, the system will display the login messages of the day. please read these carefully. Any system changes, downtimes, notices, etc., will be shown here. <P> <U><B>How to Connect to and Disconnect from <i>bsu-cs</i> </B></U> <P>YOU will be able to connect to <i>bsu-cs</i> from various locations including RB 369, 355, 356, 134, the student modem pool, from your VAX account, etc. The methods used in each location varies and are described below. Be sure to gain experience with each of the cs lab rooms as it is possible that RB 369 will be crowded when open. <P> <U><B>RB 369</B></U>: When you sit down at a machine in RB 369, you should see a screen that says "<B>welcome to <I>machine-name</I></B>" . Be sure to select (click on) <TT><B>session</B></TT>, then select <TT><B>Default</B></TT>. Enter your username and password for your unix account. Press the right mouse button on the desktop to activate a pop-up menu. From the menu, choose <TT><B>Add</B></TT> then choose <TT><B>Terminal</B></TT>. . This will open a terminal window to the local workstation (the one at which you are sitting). You may open additional windows by again using the right mouse button and the same sequence of steps. To connect to <I>bsu-cS</I>, you may enter either the command <b><TT>rlogin bsu-CS</TT></b> or the command <b><TT>telnet bSU-CS</TT> </b>. <P> To disconnect from <I>bsu-cS</I>, you need only enter the command <TT>109out</TT>; however, you stlll need to disconnect from the local workstation. To do so, click on the <b>Gnome foot</b> in the lower left hand corner of the screen and choose <b>Logout</b>. From the window that opens, choose <b>Logout</b> and click <b>Yes</b>. <p> <U><B><FONT SIZE=3>oo NOT TURN OFF THE MACHINES IN RB355, RB356 or RB369!<BR> </FONT></B></U> <BR> <U><B>RB 355/356</B></U>: When you sit down, you should be looking at a screen with a box that has a <U><B>U</B></u><B>ser name</B>, in which you should enter <TT><FONT FACE="courier New">RB355</FONT></TT> 1 c:\Download\thesis\unixsys.htm or <TT><FONT FACE="Courier New">RB356,</FONT></TT> depending on your location.

You may now login. Logging out from your account will disconnect the machine from <I>bsu-cs. </1> <P> <B>Dial-up:</B> Choose option 2, the unix system and then type return. <P> <U><B>Mail </B></U> <P> Mail is one of the most commonly used applications on any multi-user computer. The unix system currently has two mail applications, <I>mail</I> and <I>elm</I>. <I>Mail</I> is the standard issue for a unix system and <I>elm</I> is a public domain software package that is menu driven and more screen oriented. This handout will instruct you in the use of <I>elm</I>. The mail utility <I>elm</I> on <I>bsu-cS</I> can be invoked by: <P> <TT>% elm</TT><return> <P> The first time you invoke <I>elm</I>, it will ask you to set up a couple directories in your home directory. Once those directories are created, it will then show a screen similar to the following: <P> <TT><FONT SIZE=2 FACE="courier New">Mailbox is '/var/mail/john with 1 message [ELM 2.4 PL11] </FONT></TT> <P> <TT><FONT SIZE=2 FACE="Courier New"> 1 Oct 21 Henry Markum (19) HOW'S life? </FONT></TT> <P> <TT><FONT SIZE=2 FACE="Courier New"> You can use any of the following commands by pressing the first character:</FONT></TT> <P> <TT><FONT SIZE=2 FACE="Courier New">d)elete or u)ndelete mail, m)ail a message, r)eply or f)orward mail, q)uit</FONT></TT> <P> <TT><FONT SIZE=2 FACE="Courier New"> To read a message, press . j = move down, k = move up, ? = help </FONT></TT> <P> <TT><FONT SIZE=2 FACE="Courier New">command:<BR> </FONT></TT> <P> <I>Elm</I> sorts the mail file in the reverse order of time and date and displays the latest mail messages first with the real name and subject line of each message. The current mail message is highlighted. TO change the current mail message to another one, simply use the arrow keys to scroll through the list. The paragraph at the bottom of the screen displays the most common commands for <I>elm</I>. These commands use the letter before the parenthesis to choose the command. The elm system uses <I><B>vi</B></I> as the default editor for mail messages, but this can be changed by choosing <1>0 (options)</I> and changing the editor line in the options list. 2 C:\Download\thesis\unixsys.htm <P> TO send mail to someone at <I>bsu-cS</I>, you must only enter the username for the address. To send mail to someone at another site (VAX, another university, etc.) you must enter the host address of the computer where the person has an account. The form for a remote address is as follows: <TT><FONT SIZE=2 FACE="Courier New">remote_username@ hostaddress</FONT></TT> For example, for a mythical account <TT><FONT SIZE=2 FACE="Courier New">john</FONT></TT> on the <I>bsu-cS</I> system, the entire address would be: <TT><FONT SIZE=2 FACE="Courier New">john@bsu-cs.bsu.edu</FoNT></TT>. <P> <u><B>printer Access </B></U> <P> There are many printers that can be accessed from the unix system. Printers are named by their location (building and room number). For example, the printer in RB 369 is named prb369, those in RB 355 are named prb355. It is usually best to send your printouts to the room in which you are working. The command to print a document in RB369 is: <TT> %lpr -prb369 filename </TT>. <hr> <br> <p align="center"> <a href=''http://VNNJ.bsu.edu/home.html'' taraet="_top"> <img src="gifs/home.gif" border="O" WIDTH=tf72" HEIGHT="14"> <fa> <a href="mailto:ASKBSu@bsu.edu" target="_top"> <img src="gifs/ask.gif" border="O" WIDTH="72" HEIGHT="14"> <fa> <a href=''http://VNNJ.bsu.edu/cgi-bin/guest'' taraet="_top"> <img src="gifs/guest.gif" border="O" WIDTH="72 ff HEIGHT="14"> <fa> <a href=''http://VNNJ.bsu.edu/uP/about/bsu.html'' target="_t0p'''> <img src="gifs/about.gif" border="O" WIDTH="72" HEIGHT="14'> <fa> <a href=''http://VNNJ.bsu.edu/uP/map'/indiana.html'' target="_top"> <img src="gifs/map.gif" border="O' WIDTH="72" HEIGHT="14"> <fa> <a href=''http://VNNJ.bsu.edu/htmls/search.html'' target="_top"> <img src="gifs/search.gif" border="O" WIDTH="72" HEIGHT="14"> <fa> <a href=''http://VNNJ.bsu.edu/home_help.html'' target="_top"> <img src="gifs/help.gif" border="O" WIDTH="72" HEIGHT="14"> <fa> <br> <font size="-l"> <a href="mailto:rawilson@bsuvc.bsu.edu">Author</a> I Last update: <SCRIPT>document.write(document.lastModified);</sCRIPT> I <a href="mailto:rawilson@bsuvc.bsu.edu">Technical comments to the webmaster</a> </font> <br> <font size="-4"> Ball state university practices equal opportunity in education and employment and is strongly and actively committed to diversity within its community. </font> </p> <p align="center"> <em> <font size="-4"> Links contained in this file to information provided by organizations other than Ball state university's computer Science Department are presented as a service and neither constitute nor imply endorsement or warranty. </font> </em> </p> <BODY> </HTML> 3 ~ ~ Simple vi Commands wysiwyg://fill. 98lhttp://www. cs.bsu.edul-raw/thesis/vicmds.htm Simple vi (vim) Commands (There are many more!

The coding is very simple and demonstrates the main structure of the programming language as well as how to do output to the screen. Below is the code for Hello World in C++. Code appears in red text and comments appear in green text. #include <iostream.h> //Required for input-output int main () { cout « "Hello World!" « endl; return 0; This program isn't very large but it demonstrates the very basic structure of all c++ programs. At the top of the program are the include statements. The include statements instruct the compiler to insert code into this c++ program from the files found in the include files. This is an easy way to use code that has been standardized and tested and enables common features. For instance, #include <iostream.h> allows c++ programs to use cin and couto cin is used for reading in information from the user and cout is used to print information to the screen. In Hello World, the int main() function follows the include files. All C++ programs have a main function that is usually declared as type into The body of the function is the code that is found in between the brackets {} of the function. In this case, the entire program is found in the body of main. The body of the program consists of a single cout statement. This cout statement prints the words "Hello World!" to the user's screen. The return 0; statement is necessary if main is declared an into So, all programs that have an int main() function need to have a return 0; statement at the end of the body of main.
