Starting Out with Visual C#, 5e (Tony Gaddis)Chapter 4 Making DecisionsTRUE/FALSE1.The sequence structure is often used in programming because it can handle every type of task.ANS:F2.If you are writing anifstatement that has only one conditionally executed statement, you mustenclose the conditionally executed statement in curly braces.ANS:F3.The equality operator is written like this:=(with only one equals sign).ANS:F4.It is often true that both sets of conditionally executed statements in anif-elsestatement areexecuted.ANS:F5.Anyif-else-ifstatement can be coded, alternatively, as a nestedif-elsestatement.ANS:T6.In order for an&&expression to betrue, only the expression on one side of the&&operator needs tobetrue.ANS:F7.If the expression on the left side of the||operator istrue, the expression on the right side is notchecked.ANS:T8.The==operator cannot be used to compare string expressions.ANS:F9.You should usetry-catchstatements primarily for exceptions that are beyond your control.ANS:T10.Because theTryParsemethods return eithertrueorfalse, they are commonlycalled as theBoolean expression in anifstatement.ANS:T11.Check boxes are similar to radio buttons in that they are both mutully exclusive.
