CPR 101 Welcome to Computer Skills for Programmers

Agenda Discussion Course Format and Evaluation About Programming and Scripting History of Programming Styles and Methodologies Levels

Goal of CPR101 Make you a better programmer Learn how applications and system software interact Modern network concepts, cloud computing and virtualization Numbering systems, version control and project management,

Course Format Evaluation & Success

Quiz Each class will begin with a 15 minute quiz ( 5 short answer questions) You will write 10 quizzes, the best 8 will be selected for grading If you are absent for a quiz, a mark of “0” will be assigned

News of the Week After the quiz there will be a 15 minute discussion on a current news topic You are responsible for subscribing to a news service (Activity 1- Part 1) Come prepared to participate Build vocabulary Expand knowledge beyond the classroom

Weekly Lecture Lectures are 80 minutes in length and are instructor centred Ask questions anytime during the lecture Be on time Silence cell phones Be respectful of others

Weekly Activity Weekly Activity is a 50 minute exercise for skill development and knowledge to complement the weekly lecture material Graded on completing activity and reflection notes of what you learned Must complete 9 out of 11 activities to pass the course Activities must be completed in class to receive a grade. Missed activities will receive a grade of “0”

Final Assignment The Assignment must be completed to pass the course The assignment will be worked on in teams and is worth 15% You will have in class time to complete it (last 2 weeks of class)

Graded Work

For Success …

10 Steps For Success … Review the material each week before class Take notes on course material, including solutions to any problems that arise – The first step in learning Follow technology news and come prepared to participate Thoroughly read all steps in the activity before starting Ask other students or teacher for help when needed Attend all classes and be on time Silence audible devices Focus on the task at hand – don’t multitask Review previous lecture notes to prepare for quiz Submit all graded work on time

Programming or Scripting

What is Programming or Scripting?

What is Programming or Scripting? English like commands Written in a specific language Contained in a text file called a program Give instruction to a computer Compiled into machine code Executed by CPU

Early computers First computing devices in 1800s and early 1900s were more mechanical, very basic computing. 1940s saw the use of vacuum-tube computers, room-sized. Each vacuum tube can effectively perform one binary operation.

Transistors Transistor invention in 1940s led to microchip, allowed design of smaller computers that could perform more complex tasks Smaller, computers allowed for more programming code and what we think of as modern computing devices

“It would appear that we have reached the limits of what it is possible to achieve with computer technology, although one should be careful with such statements, as they tend to sound pretty silly in five years.” John von Neumann, 1949

Short History of Programming Languages

Programming Languages Do you know of any programming languages?

1945-1959 FORTRAN (1945) First widely used high-level language LISP (1958), COBOL (1959)

1980-1989 C++ (1980) Still used heavily today

Compiled Languages C C++ C# COBOL Java

Other Languages The following are not programming languages

ArnoldC, a language devised by Finnish computer programmer Lauri Hartikka, assigns programming functions to catchphrases from Arnold Schwarzenegger movies. Some keywords: If: BECAUSE I’M GOING TO SAY PLEASE While: STICK AROUND MultiplicationOperator: YOU’RE FIRED DivisionOperator: HE HAD TO SPLIT DeclareMethod: LISTEN TO ME VERY CAREFULLY EndMethodDeclaration: HASTA LA VISTA, BABY AssignVariable: GET TO THE CHOPPER Return: I’LL BE BACK

“At the end whether you are scripting, coding or programming, you are providing some environment like a PC, robot, or browser, a set of instructions on what tasks it needs to perform. Whether the language you do this is high level or low level has nothing to do with it. Whether it ends in “script” or ends in “++” has nothing to do with it. Whether it runs on your browser or on a mainframe has nothing to do with it. Whether it is intended to be sold to millions or just used by you has nothing to do with it. I’d suggest you use none of the above terms. You’re a software craftsman. You design and build solutions using the best suited technologies for the problem you are trying to solve.” Nael Shawwa at http://www.naelshawwa.com/scripting-coding-programming/
