Course Administration

• Tutorials
• Weekly once as per the time table
• From 06 -08 -07 onwards conducted in IPC
• Should attend only registered section
• Attendance is compulsory
• Focus on practical aspects of programming and
  complex problem solving
• Self learning requirements
• Class work will require students further
  exploration

• 1 written test1 20 (CLOSED)
• 2 written test2 20 (OPEN)
• Labs 20 (CLOSED)
• Comprehensive Exam. 40 (CLOSED)
• Make-Up for Tutorial cum Labs
• NO Make Up for Labs.

5
Course Administration

• Lab distribution
• Problem solving and Implementation (in C)
• Aided Labs Best 5 out of 7 ? (3M each)
• 5x3 15M
• Un-aided Labs Best 3 out of 4 ?(15M each)
• Comprehensive Exam. 40 (CLOSED)

6
Course Administration

• Make Up policy (read carefully)
• More stringent
• Requires prior permission or confirmation letter
  from the concerned Warden in addition to other
  supporting documents
• Grievances
• Meet the concerned tutorial instructor only
• Meet the I/C only when above channel fails

• Dynamic Data Storage
• Program Structuring
• Recursive Definitions
• Advanced Programming

9
Course Motivation

• Programs
• Programming
• Software Lifecycle
• Process

10
Programs

• Programs are specifications of solutions to
  problems. They
• are unambiguous.
• are formal (i.e., should be constructed
  systematically out of basic steps)
• are executable (by a machine or even by a human
  brain within limited scale)
• have predictable and repeatable results.

11
Programs

• Definition
• A program is a formal, unambiguous and
  executable specification of a solution to a
  problem

12
Programs

• Observations
• executable by machine requires formal and
  unambiguous.
• formal and unambiguous implies repeatable and
  predictable.
• Question Does formal and unambiguous imply
  executable by machine?

13
Programs

• Not so obvious but yes formal and unambiguous
  does imply executable by machine.
• (Reasonable) Assumptions basic steps are
  realizable in finite time using finite space.

14
Programs

• Alternative (equivalent) definitions of a
  Program
• A formal and unambiguous specification of a
  solution to a problem.
• An executable specification of a solution to a
  problem.

15
Course Motivation

• Programs
• Programming
• Software Lifecycle
• Process

16

• The process of constructing programs
• It is an engineering activity!
• Limited resources (Time, Hardware and Software)
• Program is the resultant product
• Typical engineering activities apply design,
  implement and test

17
Course Motivation

• Programs
• Programming
• Software Lifecycle
• Process

18
Software Lifecycle

• All products have a life after production.
• Hallmark of good engineering
• Ability to determine post-production behavior
  during the production process
• Applies for software as well
• But post-production life for software is
  different from that of other products!
• Eg Car production? post-production behavior is
  repairing the parts etc..
• Software ? Maintenance Able to reuse

19
Software Lifecycle

• Software is (expected to be) re-usable
• by any number of people
• any number of times
• for any number of purposes
• in any number of contexts and environments
• Implication
• Production Process is critical!
