  1. Introduction to Programming Lecture No. 1

  2. Program “A precise sequence of steps to solve a particular problem”

  3. Alan Perlis – Yale University: “It goes against the grain of modern education to teach children to program. What fun is there in making plans, acquiring discipline in organizing thoughts, devoting attention to detail and learning to be self-critical? “

  4. Critical Skills • Analysis • Critical Thinking • Attention to Detail

  5. Design Recipe To design a program properly, we must: • Analyze a problem statement, typically expressed as a word problem • Express its essence, abstractly and with examples • Formulate statements and comments in a precise language • Evaluate and revise the activities in light of checks and tests

  6. PAY ATTENTION TO DETAIL • These skills are useful for anybody • All assignments in this course should follow the these guidelines

  7. Computers are STUPID

  8. Humans are even more…….

  9. Think Reuse

  10. Area of the Ring Area of Outer Circle = Area of the Ring

  11. Think Reuse • Think User Interface • Comments liberally

  12. What is the probability that she gets exactly three letter right i.e. three Letters into their correct envelopes.

  13. Logical Error Lewis Carol: “Through the Looking Glass” “Twas brillig, and the slithy toves Did gyre and gimble in the wabe “

  14. Course Policy Quizzes : 10 % One Hour Tests : 30 % Lab : 5% Assignments : 5% Project : 5 % Final Test : 45%

  15. Books • Deitel & Deitel :– C++ How to Program • Kernighan and Ritchie:- The C Programming Language

  16. Course Objectives Objectives of this course are three fold • To appreciate the need for a programming language • To introduce the concept and usability of the structured programming methodology • To develop proficiency in making useful software using the C language

  17. Course Contents To achieve our first two objectives we will be discussing • Basic Programming constructs and building blocks • Structured programming • Structured flowcharts, pseudo-code

  18. Course Contents • History of C Language • Variables and expressions in C • Control structures and functions • Arrays and Pointers • Dynamic memory Allocation

  19. Course Contents • File handling • Structures and Unions • Flavor of Object oriented programming • Sockets

  20. Books • Text Books • How to Program – C by H.M. Dietel / P.J. Deitel • The C Programming Language by Brian W. Kernighan, Dennis M. Ritchie

  21. Books • Reference Books (very important part) • Learning C by Neill Graham • C++, How to Program by Deitel & Deitel • Thinking in C++ by Bruce Eckel • www.cprogramming.com • www.cplusplus.com • www.howstuffworks.com • www.whatis.com

  22. Policies • Bring your own calculator, pen paper etc.. • You will not be allowed to borrow anything from anyone during any test • Must write your name and reference number (Merit No or Regn No) in a test • No late work will be accepted (unless arrangements have been made in advance) • Ask questions; participate actively in class • You are allowed to talk to instructor only
