Introduction to Computer Programming Class 1 CSCI-UA 2 Introduction and Overview “Computers and networks finally offer On Code Literacy us the ability to write. And we do write with them on our websites, blogs, and social networks. But the underlying capability of the computer era is actually programming—which almost none of us knows how to do. We simply use the programs that have been made for us, and enter our text in the appropriate box on the screen.” —Douglas Rushkoff

Introduction to Computer Programming Class 1 CSCI-UA 2 Introduction and Overview Low-level programming languages are Programming Languages closer to “machine language” Low-Level They are difficult (though not impossible) for humans to read and, as such, are more error-prone

Introduction to Computer Programming Class 1 CSCI-UA 2 Introduction and Overview High-level programming languages are Programming Languages closer to real syntax High-Level High-level languages are abstracted and therefore require interpretation We’ll be working with a high-level language

Introduction to Computer Programming Class 1 CSCI-UA 2 Introduction and Overview Syntax Natural Languages and Grammar High-Level Programming Parts of speech Languages Semantics Similarities

Introduction to Computer Programming Class 1 CSCI-UA 2 Introduction and Overview Natural language syntax is the Syntax arrangement of words and phrases to create well-formed sentences. Programming language syntax is the arrangement of words and characters to correctly structure programs.

Introduction to Computer Programming Class 1 CSCI-UA 2 Introduction and Overview Natural language grammar refers to Grammar the whole system and structure of a language, such as sentences and paragraphs. Programming languages also implement structure, such as blocks of code and statements within the blocks.

Introduction to Computer Programming Class 1 CSCI-UA 2 Introduction and Overview Natural languages incorporate different Parts of Speech parts of speech, like nouns, verbs, and adjectives. Programming languages also have parts of speech called “data types” that include different kinds numbers and characters.

Introduction to Computer Programming Class 1 CSCI-UA 2 Introduction and Overview In natural languages, semantics refers Semantics to the meaning of a word. “Cat” brings something specific to mind. In programming languages, certain symbols, like + and =, have specific meaning as well as some key words.

Introduction to Computer Programming Class 1 CSCI-UA 2 Introduction and Overview Determining the logic of a program Pseudocode without regard for the language it will be written in Best written out on paper or in a plain text editor Pseudocode describes the steps of an algorithmic process
