Unit 3 Vocabulary

Block of statements

• One or more statements enclosed in an open curly brace '{' and a closing curly brace '}'.
• used to start a conditional statement. This is followed by a statement or a block of statements that will be executed if the Boolean expression is true.
• Used to execute the following statement or block of statements if one of the conditions are true
• used to execute a statement or block of statements if the Boolean expression on the if part was false.

Boolean expression

• A Boolean expression with two or more conditions joined by a logical and '&&' or a logical or '||'.
• A mathematical or logical expression that is either true or false.
• One or more statements enclosed in an open curly brace '{' and a closing curly brace '}'.
• used to start a conditional statement. This is followed by a statement or a block of statements that will be executed if the Boolean expression is true.

complex conditional

• used to have 3 or more possible outcomes such as if x is equal, x is greater than, or x is less than some value. It will only execute if the condition in the 'if' was false and the condition in the else if is true.
• used to start a conditional statement. This is followed by a statement or a block of statements that will be executed if the Boolean expression is true.
• Used to execute code only if a Boolean expression is true.
• A Boolean expression with two or more conditions joined by a logical and '&&' or a logical or '||'.

conditional

• Used to execute code only if a Boolean expression is true.
• Rules about how to distribute a negation on a complex conditional.
• used to have 3 or more possible outcomes such as if x is equal, x is greater than, or x is less than some value. It will only execute if the condition in the 'if' was false and the condition in the else if is true.
• A Boolean expression with two or more conditions joined by a logical and '&&' or a logical or '||'.

DeMorgan's Laws

• turns a true statement false and a false statement true
• used to execute a statement or block of statements if the Boolean expression on the if part was false.
• Rules about how to distribute a negation on a complex conditional.
• Used to execute the following statement or block of statements if one of the conditions are true

logical and

• Used to only execute the following statement or block of statements if both conditions are true
• Used to execute the following statement or block of statements if one of the conditions are true
• used to start a conditional statement. This is followed by a statement or a block of statements that will be executed if the Boolean expression is true.
• A Boolean expression with two or more conditions joined by a logical and '&&' or a logical or '||'.

logical or

• One or more statements enclosed in an open curly brace '{' and a closing curly brace '}'.
• Used to only execute the following statement or block of statements if both conditions are true
• Used to execute the following statement or block of statements if one of the conditions are true
• turns a true statement false and a false statement true

negation

• turns a true statement false and a false statement true
• Rules about how to distribute a negation on a complex conditional.
• used to start a conditional statement. This is followed by a statement or a block of statements that will be executed if the Boolean expression is true.
• Used to execute code only if a Boolean expression is true.

short circuit evaluation

• The type of evaluation used for logical and '&&' and logical or '||' expressions. If the first condition is false in a complex conditional with a logical and the second condition won't be evaluated. If the first condition is true is a complex conditional with a logical or the second condition won't be evaluated.
• used to have 3 or more possible outcomes such as if x is equal, x is greater than, or x is less than some value. It will only execute if the condition in the 'if' was false and the condition in the else if is true.
• used to execute a statement or block of statements if the Boolean expression on the if part was false.
• Used to execute code only if a Boolean expression is true.

if (Boolean expression)

• A Boolean expression with two or more conditions joined by a logical and '&&' or a logical or '||'.
• The type of evaluation used for logical and '&&' and logical or '||' expressions. If the first condition is false in a complex conditional with a logical and the second condition won't be evaluated. If the first condition is true is a complex conditional with a logical or the second condition won't be evaluated.
• used to start a conditional statement. This is followed by a statement or a block of statements that will be executed if the Boolean expression is true.
• turns a true statement false and a false statement true
