COMPUTER SCIENCE 10: INTRODUCTION TO COMPUTER SCIENCE

Dr. Natalie Linnellwith credit to Cay Horstmann and Marty Stepp

Who am I?

How I teach

Teaching is my favorite thing! Your involvement is important

Lots of questions In-class activities

Not graded, as long as you participate In class we will be writing code, and I will post

it after class My philosophy on my job: It is your job to

learn, and it is my job to help you do that.

Who are you?

What’s your major? Year? Why are you taking this class? Do you have any programming

experience? Something else about yourself

Take this course if you…

… like solving tricky problems

… like building things

… (will) work with large data sets

… are curious about how Facebook, Google, etc work

… have never written a computer program before

… are shopping around for a major

Course Challenges

Prerequisites? Math11 …Really, no experience required!

Aptitude? Most people can learn basic programming

Interest? CS is creative and rewarding, but it can also be time-consuming

Time? You can't expect to learn complex skills by listening to lectures This class will probably have the heaviest workload of any of your

classes this term Study habits?

Your brain needs time to learn. Don't try to do all work the night of the due date

You need time to get stuck, ask for help, get unstuck, get stuck again…

Jobs before graduation

High-demand for talent

Diverse opportunities

Software shops (Microsoft, Amazon, Google, Facebook…)

Hard sciences (computational biology…) Engineering (simulations…) Healthcare (data management…) Education (math…) International development (data

gathering…)

Course goals

Be able to apply your understanding Computer Science is different! Programming is a skill

By the end of the course, you will: write medium-scale programs to solve real

problems know some of the kinds of problems

computers can solve recognize beautiful code recognize ugly hacks

What is programming?

program: A set of instructionsto be carried out by a computer.

program execution: The act ofcarrying out the instructions contained in a program.

programming language: A systematic set of rules used to describe computations in a format that is editable by humans.

What do we notice about your programs?

“Language”

Compiling/running a program1. Write it.

code or source code: The set of instructions in a program.

2. Compile it.• compile: Translate a program from one language

to another.

3. Run (execute) it. output: The messages printed to the user by a

program.

With Code::Blocks

You are learning to do something There is no way to fake your way through

this class.
