What is Programming

• Programming is a set of instructions for the computer to do
• There are many languages such as, Java, C++, Processing, etc.
• AP CSP is language neutral
• Writing code is very specific; explicit
• Low Level programming language is machine oriented
  • Specific to the processor (assembly language)
• High level languages easier to understand by and closer to spoken language
• APCSP uses Pseudocode to represent code
• Only describes ideas common across different languages

ABSTRACTION

• Process of simplifying concept in order to make the task easier and simpler
• reducing complexity and allowing for efficient design
• displaying essential info and hiding detail
• Variables are abstractions
• RANDOM(a,b) is an abstraction (a function)

IN JAVA/PROCESSING

• random(1,5);
  • random floating number
• type casting can be used to make it an integer
  • int(random(1,5));
    • random integer
• 7/2=3
