Programming

Programming

1. Algorithm - a set of instructions used to solve a problem

2. Sequencing - the computer executing the commands in an order

   • Iteration - to repeat to get a desired outcome
     • for loop - defines a counting variable that is checked on each iteration to loop a specific number of times
     • loop - a programming construct that repeats a group of commands

3. Selection - a statement that causes you to choose something (i.e., if statements)

4. Top Down Design - a problem solving approach in which you break down a system to gain insight into the sub-systems that make it up

5. High-Level Languages - computer programs

   • Low-Level Languages - the language the computer speaks (i.e., binary)
   • Turtle Programming - a classic method for learning programmming with commands to control movement and drawing of an on-screen robot called a "turtle"
   • Abstraction - a simplified representation of something more complex
     • Function - a named group of programming instructions
       • Parameter - an extra piece of information that you pass to the function to customize it for a specific need
   • Hexadecimal - a base-16 number system that uses sixteen distinct symbols, 0-9 and A-f, to represent numbers from 0-15

6. API - a collection of commands made available to a programmer

   • Documentation - a description of the behavior of a command, function, library, etc.
   • Library - a collection of commands/functions, typically with a shared purpose
