| |
| − | Many of the CS courses use C and C++. If you are a new graduate student or a transfer student, you should get started by making sure you can connect to the CS server with Putty or another terminal program. Once you can connect, you should familiarize yourself with linux shell commands (see the Unix/Linux Quick Reference Card linked above). You should also learn to use one of the text editors mentioned above.

| |
| − | For CS courses that use C and C++, the gcc and g++ compilers are normally used. These are already installed on the CS server. If you have a C or C++ program, you compile it by first logging into the CS server using Putty or another terminal program and typing

| |
| − | for C, or g++ for c++. You run the resulting program by typing ./outputName (and then enter/return) at the shell prompt (aka command line). You should make sure your C/C++ programs compile and run using gcc/g++. Note that programs made using MS Visual Studio or some other compiler will normally not work straight away with gcc/g++ because there are some differences in which functions are included in the header files.

Once you are reasonably familiar with all the syntax rules, start trying "programming contest problems". These are problems with precisely defined correct output, so that you can submit your program to make sure it is 100% correct.

This section contains information for CS majors to help get you started with logging into the CS server and do the sorts of programming that goes on in most of the CS courses
Operating System and Class Accounts
Many of the CS courses make use of the CS server, which runs Linux. For courses that use the CS server, your programming assignments will be compiled and run on the CS server.
If your class makes use of the CS server, you will be given a "class account". These class accounts allow you to login to the CS server remotely and login to the computers in the CS lab and classroom (Root Hall, A-015, A-017, A-019). The class accounts will be given to you by your instructor. The class account login names all start with cs and then the number of course. For example, CS 151 students get class accounts that begin with cs151 (e.g., cs151000, cs151001, ...). Note that the class accounts are deleted at the end of each semester. If you are a CS major and would like a permanent account on the CS server you can ask your instructor.
For courses using the CS server, you are encouraged to do your programming while logged into the server (e.g., using Putty from Windows, or another terminal client if using another OS). You should use the same program to compile/run your code that the instructor uses, so you are sure it will function properly when your instructor grades your code.
Using Linux and Logging into CS Systems
