Scripting and Programming
Foundations - D278 Exam|Complete
Questions with Answers A+ Graded
Three basic instruction types - -Input, process, output
- Computational thinking - -Creating a sequence of instructions to solve a
problem (aka algorithm)
- Algorithm - -A sequence of instructions that solves a problem
- Flowchart - -A graphical language for creating or viewing computer
programs
- Coral Code Language - -A language intended for learning to program
Two versions: flowchart and code
Looks like pseudocode, but follows rules that allow execution
- Program - -A list of statements
Each statement is carrying out some action and executing one at a time
- String literal - -consists of text (characters) within double quotes
Ex: "Go #57!".
- Cursor - -Indicates where the next output item will be placed in the next
output
The system automatically moves the cursor after the previous output item
- Newline - -\n
Special sequence who appearance in an output string literal causes the
cursor to move to the next output line
Exists visibly in the output
- Comment - -// this is an example of a comment
Text a programmer adds to a program to be read by humans but ignored by
a program when executing
Use // before the comment
Includes the entire line of text.
, - White space - -Refers to blank spaces between items within a statement
and to newlines
Improves readability
Ignored in execution
- Moore's Law - -Observation that switch sizes reduce by half every two
years
- Bit - -A single unit of binary consisting of only one place whose value can
be 0 or 1.
- Byte - -8 bits
- ASCII - -A popular code for characters
- Pseudocode - -Text that resembles a program in a real programming
language but is simplified to aid human understanding.
- Variable - -A named item used to hold a value
- Assignment statement - -Assigns a variable with a value; and keeps that
value during subsequent statement until X is assigned again.
Assignment's left side must be a variable (ex. x=5)
- Variable declaration - -Declares a new variable, specifying the variables
name and type
- Integer variable type - -Can hold whole number values
- Expression - -A combination of items like variables, literals, operators, and
parentheses that evaluate to a value
Ex.) y=2*(x+1)
- Identifier - -A name created by a programmer for an item like a variable or
function
Must be a sequence of letters, underscores, and digits
Must start with a letter
Case sensitive
- Reserve word - -A word that is part of the language like: Integer, Get, or
Put
Cannot use as an identifier
