- Switch on your monitor.
- Switch on your PC.
- Allow the machine to boot. Wait till the login
- Supply your login and password:
Here <nn> is the number of your PC. This opens
your window manager (usually KDE) with icons, the bottom
panel and so on. You are now ready to start your work.
- Click on the terminal icon to open a shell
- You may create other windows from the first one by typing
xterm & and then pressing
- A window must be active for
you to type anything in it.
To make a window active move the mouse
pointer to the upper horizontal bar of the window, and press the lest button
of the mouse.
- Edit your program (new or already existing) by an
editor. We recommend using the emacs editor. This is how you can
emacs myprog.c &
(Note that the ampersand in the last command was not
necessary, but is helpful in the sense that it runs emacs in the background
and the shell is free to listen to your other commands.)
- Write your program in the editor and save it.
- Go to the shell and compile your program:
If compilation is successful, an executable called
a.out will be created.
- Run your program:
You may have to give the command ./a.out in case
you are issued a message like a.out: Command not found.
- Continue your edit-compile-debug-run-debug-print work.
Finally, it's pretty late. It's time to pack up. Wait! You
still have some more things to do, before you rush for your lunch.
- Close all the windows you opened.
- Logout from your window manager. This leaves you
again in the login console.
- Select the item to shut down the machine. Wait till
the machine completely shuts down.
- Switch off your monitor.
- You can now leave. Don't remember later that you have
forgot to sign the attendance sheet. You may not rely on our memory to certify
in the next week that you were present in this lab session.
