Program Consists of instructions executing one at a time.
Input A program gets data, perhaps from a file, keyboard,
touchscreen, network, etc.
Process A programs performs computations on that data, such as
adding two values like x + y.
Output A programs puts that data somewhere, such as to a file,
screen, network, etc.
Computational thinking Creating a sequence of instructions to solve a problem.
Algorithm A sequence of instructions that solves a problem.
, Statement Carries out some action and executing one at a time.
Consists of text (characters)
within double quotes,
String literal as in "Go #57!".
Indicates where the next output
item will be placed
Cursor in the output.
Newline A special two-character sequence \n whose appearance
in an output string literal causes the cursor to move to
the next output line. The newline exists invisibly in the
output.
Text added to a program, read by
humans to
Commentunderstand the code, but ignored by the program
when executed.
Whitespace Refers to blank spaces (space and tab characters) between
items within a statement, and to newlines. Whitespace
helps improve readability for humans, but for execution
purposes is mostly ignored.
Pseudocode Text that resembles a program in a real
programming language but is simplified to aid
human understanding.
Assignment statement Assigns a variable with a value, such as x = 5. An assignment
statement's left side must be a variable. The right side is an
expression.Examples: x = 5, y = a, or z = w + 2.
= In programming, = is an assignment of a left-side
variable with a right-side value. It does not represent
equality like in mathematics.
Declares a new variable, specifying the variable's name and
Variable declaration
