Live preview is available on a touch screen T/F
TEA [102]
<span>It is false that live preview is available on a touch screen. Life preview refers to cameras mostly, and to the fact that its display screen can be used as a viewfinder. Viewfinder is what you look through when you are using a camera to take a photo, or to focus on something. So, no, touch screen devices do not have this feature available, only the "old-school" cameras do.</span>

Consider the following methods:
il63 [147K]
<span>2. basketball This is a classic case of overloading in C++. You have 2 functions, both named "printSport", but one of the functions receives an input of type double, and the other receives an input of type int. The specified method call passes a parameter of type int, so the version of printSport is called that receives a parameter of type int. And that version of printSport only prints the word "basketball". The other version of printSport is never called at all.</span>
