Pushpak Bhattacharya

Course Organization

Computers everywhere

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

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

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

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 Organization

• Lectures ( twice a week )– Monday, Thursday 8:30 to 9:30 or 14:00 to 15:00

• Tutorials (once a week)– Wednesday 15:00 to 16:30

• Labs. (once a week)– Monday to Friday – 18:00 to 20:30 and 20:30 to 23:00

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

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

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

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)

Evaluation

• end semester examination – 50 %• mid semester examination – 30 %• two/three quizzes – 10 %• lab+project – 10 %• all exams will be closed book and notes• emphasis on developing and writing good,

correct programs for various problems• quizzes conducted during tutorials

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)

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

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

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)
