Course Philosophy

• Computer Science Side• Problem Solving• Logical Thought• Programming in C++

19

Course Philosophy

• “Real World” Side• Human Nature• Corporate World• Surviving during and after College

20

Problem Solving

• Arrange a deck of cards by suit and rank

• How would you do this?

• How would you tell a child to do this?

• How would you tell a computer to do this?

21

Problem Solving

• CS 105 develops logic skills to solve problems by writing a program.

• A program is a problem-solving tool.

• Computers follow instructions they’re given.

• They don’t have “intuition” or make decisions “on their own”.

22

Why Use a Program?

• Computers perform tasks many times faster than a person.

• Computers are more consistent than a person.

• Computers can work 24-7.

23

Terminology• Source Code: The original problem-solving, logical

solution written in a programming language (e.g. C++)

• Compiling: The action of turning the source code into a format the computer can use.

• Linking: The action of bringing in already written code (Libraries) for use in a new program.

• Executable: The result of compiling and linking a source program; the “.exe” file that the computer can run

24

C++ Required Elements

• Every C++ program must have:

• int

• main()

• {

• }
