Conditional Statements

• slides
• Cannot do a switch on a variable of type double
• Any switch can be converted to an if-elseif, but an if-elseif may not be able to be converted to a switch

Blackjack (In-Class Project)

• Finish initial phase of development and address some problems.
• Modify Friday's BlackJack program so that it (1) generates the cards randomly and (2) prints the two cards in the hand, as well as the score.

Conditional Statements

• Conditional statements let us execute different code based on whether or not something is true.
• Standard conditional statements are: if, if-else, if-elseif-elseif..., switch.
• if-elseif versus switch statement.
• Single "=" is assignment, double "==" is a test.
• Less than: <. Greater than: >. Less than or equal to: <=. Greater than or equal to: >=.
• "&&" is and, "||" is or (on my keyboard, "|" is on the same key as the "\").
• See sample code above for examples.
