Introduction

About CS149

• This class is about problem solving and using programming to implement your solutions
• Algorithm:
  A series of steps for solving some problem that are detailed and clear enough that anyone following them will produce the correct output.

Components of creating a solution

• Two parts:
  • Algoritm design: Creating a set of steps for solving the problem.
  • Programming: Translating those steps into a language that a computer can execute
• We will be programming in Python. Specifically Python 3.

CS149 Logistics

• This course does not assume you have any background in programming
• This is not a weed-out course, but a B- or higher is required to move on to CS159 and a B average in CS149 and 159 to move into the major/minor

Some vocabulary

• Identifiers: names the programmer chooses
• Keywords: names already in the programming language
• Separators (also known as punctuators): punctuation characters and paired-delimiters
• Operators: symbols that operate on arguments and produce results
• Literals (specified by their type)
  • Numeric: int and double
  • Logical: boolean
  • Textual: char and String
  • Reference: null
