MIS 505 Chapter 4: Making Decisions PART 1




TRUE/FALSE

	1.	Every decision you make in a computer program involves evaluating a Boolean expression.


	2.	In any Boolean expression, the two values compared can be either variables or constants.


	3.	Any decision can be made using combinations of just two types of comparisons: equal and not equal.


	4.	Most programming languages allow you to ask two or more questions in a single comparison.


	5.	A short-circuit evaluation is where each part of an expression is evaluated only as far as necessary to determine whether the entire expression is true or false.


	6.	When you need to satisfy two or more criteria to initiate an event in a program, you must make sure that the second decision is made entirely independently of the first decision.


	7.	Besides AND and OR operators, most languages support a NOT operator.


	8.	Most programming languages limit the number of AND and OR operators in an expression.


	9.	When you combine AND and OR operators, the OR operators take precedence, meaning their Boolean values are evaluated first.


	10.	You can use parentheses to override the default order of operations.
