THINKING OBJECTSIf you have not programmed with classes before, it can take a little while to get the feel of pro-gramming with them. When you program with classes, data rather than algorithms takes center stage. It is not that there are no algorithms. However, the algorithms are made to fit the dat[r]

type int.)Now consider numbers greater than or equal to 2.5; for example, 2.6. The value returned by the call round(2.6) is the following (converted to an int value):floor(2.6 + 0.5)which is floor(3.1), or 3.0. In fact, for any number that is greater than 2.5 and less than or equal to 3.0, that numb[r]

getInput(inputNumber); C++ allows you to place the ampersand either with the type name or with theparameter name, so you will sometimes see void getInput(double &receiver); which is equivalent to void getInput(double& receiver); Display 4.2 demonstrates call-by-reference parameters.[r]

Inline functions are more than just a notational variant of the kind of member func-tion definitions we have already seen. The compiler treats an inline function in a specialway. The code for an inline function declaration is inserted at each location where thefunction is invoked. This saves the over[r]
