Unit 4 Coding

Expression

• a combination of operators and values that evaluates to a single value

• allows a program to change the value represented by a variable

• permanent can be used anywhere in your code

• holds one value at a time

Variable

• holds one value at a time

• a combination of operators and values that evaluates to a single value

• allows a program to change the value represented by a variable

• temporary can only be used in the part of the code where it was created like inside and on event.

Assignment Operator

• allows a program to change the value represented by a variable

• holds one value at a time

• a combination of operators and values that evaluates to a single value

• data type that is either True or False

Global Variable

• permanent can be used anywhere in your code

• temporary can only be used in the part of the code where it was created like inside and on event.

• data type that is either True or False

• a combination of operators and values that evaluates to a single value

Local Variable

• temporary can only be used in the part of the code where it was created like inside and on event.

• Evaluates to either True or False

• Your code doesn't follow the rules of programming language

• permanent can be used anywhere in your code

Boolean Value

• data type that is either True or False

• permanent can be used anywhere in your code

• A command that executes the code within a function

• <, >, <=, >=, ==, != indicate a Boolean expression

Boolean Expression

• Evaluates to either True or False

• Your code doesn't follow the rules of programming language

• Your code follows the rules of the programming language but doesn't do what you intend

• A named group of programming instructions AKA "Procedure"

• Evaluates to either True or False

Logic Error

• Your code follows the rules of the programming language but doesn't do what you intend

• A named group of programming instructions AKA "Procedure"
