3
Computers everywhere

• Ovens, washing machines and toys
• Banks Hospitals
• Transport Reservations, Signaling
• Aircraft and industrial plant controllers
• Missiles and satellites,
• and many more

4
Why so prevalent

• They solve a variety of problems
• Efficient maintenance of large no. of data
• Precise control of movements
• Automation of many boring manual processes
• In all
• They improve the quality of life

5
Your Job

• Many improvements are made and many more to come
• You, tomorrow's quality scientists and Engineers,
  are responsible for this
• You need to develop expertise in using computers,
• Ability to solve more problems using computers

6
Objectives of this course

• Broad Objectives
• Introduce use of computers
• Understand how computers work
• Give an idea of the problems solved by computers
• Develop skills for effective problem solving
  using computers
• Write programs in a high level language

Course Instructors

• Lectures
• myself, Pushpak Bhattacharya, CSE Dept.
• Tutorials
• in small batches in separate rooms (MB)
• you will know your batch soon
• conducted by teaching assistants (TA)
• Labs also conducted by TAs

9
Lectures

• introduce general concepts of programming
• Example programs to illustrate
• Focus on language independent concepts
• Less emphasis on details, as it is language
  dependent
• application of concepts more important
• concepts better learnt by reading, writing,
  compiling and running programs
• tutorials and lab for this

10
Tutorials

• Discussion of problems and their solutions
• Clarification of topics covered in lectures
• Tutorials in small batches ( 25 students)
• Each batch will have a Teaching Assistant
• Tutorials involve writing programs on paper
• Tutorial problems given at appropriate times
• Tutorials start from next week
• Details on the course web page

11
Laboratory

• Lab. for compiling and running programs
• advisable to write and analyze programs first
• tutorial problems may be used for lab.
• NO SEPARATE lab assignments
• One major project starting in the middle
• Lab - ground floor of Math's dept.
• 75 students at a time (3 tutorial batches)
• you will be assigned a time slot
• Lab. starts next week ( more details later)

12
Evaluation

• end semester examination 50
• mid semester examination 30
• two/three quizzes 10
• labproject 10
• all exams will be closed book and notes
• emphasis on developing and writing good, correct
  programs for various problems
• quizzes conducted during tutorials

13
Lab Project

• emphasis on developing a complete solution
• choose and formulate a problem
• develop ideas for efficient solution
• code and compile
• document and demonstrate
• choice of problem not important
• choose what you like most
• choose early ( before mid-semester)

14
Books

• Two easily available books on Fortran
• Introduction to Fortran 90/95, S. Chapman, Tata
  McGraw-Hill, 1999
• Introduction to programming in Fortran 90 and 95,
  V. Rajaraman, Prentice-Hall India, 1995.
• Other books for problems

15
Other Books

• How to solve it by computer, R. Dromey,
  Prentice-Hall India.
• Art of Computer Programming, Vol. I, II, III, D.
  E. Knuth, Addison Wesley.
• Emphasis on solving problems rather than textual
  material.
• Problems from mathematics / science and
  engineering

Your Conduct

• Lectures
• Non interactive
• Basic course on programming
• Course common to all I yearites
• No background assumed
• If you know,
• Please keep quiet (try to learn more)
• Strictly No talking ( free to sleep!)
• Think of your poor friends, help them

18
Your Conduct

• Tutorials
• Venue for interaction clarification
• TA s will hold
• Make full use of them
• Labs.
• Hands-on experience very essential
• Again make full use of the labs. (free labs.
  possible)
• Strict observance of rules given in the web page
  (be aware of them)
