Overview of the course

• C programming
• Unix programming - C shell - basic unix commands
• C++ programming - introduction

Homework

• An assignment every two weeks
• singleton submission
• assignments are worth 20% of total grade
  • final exam is worth 80%

Homework Issues

• you can use your home computer
• you can use your friend’s computer
• you can use any computer you like
• but the programs you submit must work on the Unix system in the lab.
  • you use any of the options above at your own risk
• see Submission Guidelines for precise instructions

Working from home at your own risk

• develop the code with the available tools
• copy the files that contain the source code later to the university
• compile again at the univerisy to verify that everything works

Developing at home

• locally - on a local machine
• remotely - on a university machine

Developing on a local machine (at home)

• install linux - if you are brave!
• install cygwin - a UNIX environment for Windows
  1. a DLL (cygwin1.dll) which acts as a UNIX emulation layer providing substantial UNIX API functionality.
  2. a collection of tools, ported from UNIX, which provide UNIX/Linux look and feel

Windows

• install a few tools including the gnu compiler from cygwin
• use Dev-C++ - a full-featured Integrated Development Environment (IDE) for Win32. Thank you Assaf Lavie for pointing it out to me.
  • Uses GCC, Mingw or Cygwin as compiler and libraries set
• use Microsoft tools from the command line
  • you need to add the directory where all the tools are to your search path (PATH environment variable)
• use MSVC project
  • developing C\C++ using Microsoft Visual C++ 6.0, courtesy of the system dep.English Hebrew

Copying Files and Accessing the Unix computers in CS

• use WinSCP to copy files (secure copy protocol)
• use SSH to login relotely (secure shell)
• visit the system for all the relevant information and downloads

Account, labs, printing, and email

• if you don't have an account on the Unix system, you need to open one
• if you have an account, make sure you change your password

  passwd

• list of printers and instructions can be found at system FAQ for printing
• all sorts of useful information at the system FAQ http://www.cs.tau.ac.il/faq

so let's look at the whole process

• write a program
  • text editor
• compile the program
  • C compiler
  • will do one of two things:
    • print error messages and abort
    • produce an executable program
• run the program

Editors

• vi - a programmers text editor
• pico - simple text editor in the style of the Pine Composer
• emacs - GNU project Emacs
  • the user functionality of GNU Emacs encompasses everything other Emacs editors do, and it is easily extensible since its editing commands are written in Lisp
  • xemacs - a version of emacs
  • .emacs - an initialization file example
• Dev-C++ built in
• Microsoft - MSVC project built in (only on windows...)
• Editor of your choice
