MIS 505 Final Exam Review 7 Chapter 4: Making Decisions > latest complete questions and answers Complete Solution.

Questions: Review 7 Every decision you make in a computer program involves evaluating a Boolean expression. In any Boolean expression, the two values compared can … either variables or constants. An y decision can … made using combinations of just two types of comparisons: equal and not equal. Most programming languages allow you to ask two or more questions in a single comparison. 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. 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. Besides AND and OR operators, most languages support a NOT operator. Most programming languages limit the number of AND and OR operators in an expression. When you combine AND and OR operators, the OR operators take precedence, meaning their Boolean values are evaluated first. You can use parentheses to override the default order of operations. A selection with an action that is associated with each of two possible outcomes is known as a(n) ____ selection. The keyword that is NOT included in a single-alternative selection is ____. Boolean expressions are named after ____. ____ operators require two operands. The ____ sign means “greater than.” Usually, ____ variables are not considered to … equal unless they are identical. When you ask multiple questions before an outcome is determined, you create a ____ condition. A(n) ____ decision is a decision in which two conditions must …. true for an action to take place. A series of nested if statements is also ____ if statement. Most languages allow you to use a variation of the decision structure ____ structure when you must nest a series of decisions about a single variable. Most programming languages allow you to ask two or more questions in a single comparison by using a(n) ____ operator that joins decisions in a single statement. For maximum efficiency, a good rule of thumb in an AND decision is to ____. ____ evaluation is when each part of an expression that uses an operator is evaluated only as far as necessary to determine whether the entire expression is true or false. When creating a truth table, you must determine how many possible Boolean value combinations exist for the conditions. If there are two conditions, ____ combinations will exist. In a truth table, the expression ____ is true. The conditional AND operator in Java, C++, and C# is ____. ____ are diagrams used in mathematics and logic to help describe the truth of an entire expression based on the truth of its parts. A(n) ____ decision is a decision in which at least one of two conditions must … true for an action to take place. In a truth table, the expression ____ is false. For maximum efficiency, a good rule of thumb in an OR decision is to ____. C#, C++, C, and Java use the symbol ____ as the logical OR operator. You use the logical ____ operator to reverse the meaning of a Boolean expression. You can perform a ____ by making comparisons using either the lowest or highest value in a range of values. When you combine AND and OR operators, the ____ operators take precedence,meaning their Boolean values are evaluated first. You can use ____ for clarity and to override the default order of operations. Show Less
