8. Connecting to the University Linux Server
We use an SSH client to make a network connection to a remote computer (basically text-based remote desktop)
Any SSH client should work (hint for mac/linux users)
Use SSH to connect to: login.cs.auckland.ac.nz
Login using your UPI and password
You can access the Linux server from anywhere

15. Nano
Nano is a simple text editor you can use to write code while connected to the Linux server. There is a basic tutorial HERE. You can start Nano by typing the command: nano Or you can edit a specific file by typing it with the command: nano myfile.txt

16. GCC
GCC is the C language compiler we will be using. Only code which compiles using GCC version (the version found on the Linux server) will be awarded marks for assignment 2. There is a basic tutorial HERE or This command will turn your code into a program called a.out: gcc mycode.c Or you can name your program by typing a name with the command: gcc mycode.c –o myprogram Note: In Linux, compiled programs traditionally have no extension.

17. cplusplus.com Reference site for C and C++
Provides information on all standard functions
Think of it as the LC-3 Reference, but for C. (have it open when you are working)
Great place to find example code!
Also en.cppreference.com/w/c
