Description:
A LapTop object consists of three private bjects: a CPU, a Screen and a Modem. Each of these objects, in turn, has a
weight, performance (speed or size), and cost. Here is the
prototype for the Screen class, as an example:
// ----------------
class Screen prototype-----------------
class Screen
{
private:
double weight,
size,
cost;
public:
Screen(double w=3, double s=13.3, double c=215);
double GetCost();
double GetWeight();
double GetSize();
};
Using this prosaic description of the four classes, as well as
the following sample main(), and resultant output from that same
sample main(), construct all four classes, and demonstrates that
your classes work by actually running the main() supplied and
producing the output that is shown.
// ---------------- main --------------------
int main()
{
CPU cpu1, cpu2(3.4, 233, 945), cpu3(2.9, 350, 1295);
Screen scr1, scr2(1.3, 10.3, 306), scr3(1.8, 14.1, 520);
Modem mdm1, mdm2(.026, 56000, 160);
LapTop lap1,
lap2(cpu1, scr3, mdm2),
lap3(cpu3, scr2),
lap4(cpu2, scr2, mdm2),
lap5(cpu3, scr3, mdm2);
lap1.ShowSpecs();
lap2.ShowSpecs();
lap3.ShowSpecs();
lap4.ShowSpecs();
lap5.ShowSpecs();
return 0;
}
