  1. Introduction to Programming Lecture No. 1

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

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

  4. 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

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

  6. Computers are STUPID

  7. Humans are even more…….

  8. Think Reuse

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

  10. Think Reuse • Think User Interface • Comments liberally

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

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

  13. Books • C++ by Robert Lafore • Deitel & Deitel :– C++ How to Program • Kernighan and Ritchie:- The C Programming Language

  14. 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

  15. 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

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

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

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

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

  20. 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

  21. Policies • You are responsible for what is covered in class – even if you don’t show up • Deficiency in attendance may lead to termination or relegation • You are encouraged to help each other with your homework assignments – but you must turn in your own work • If you are found to be cheating, you will fail at least the assignment / test and perhaps the entire class
