Define a struct Point that has two components $x$ and $y$ of type float. Define a class Polygon that has

private data members numberOfPoints, length of type float, ${?}^{**}p$ a pointer of type Point, and

findLength$().$ The class has the public member functions set$($int$),$ get$(),$ print$(),$ a parameterized

constructor with a default value, and a copy constructor.

Implement the member functions of the class, including all #include, etc.

Sample input$/$output:

Enter the $x$ and $y$ coordinates of the $2$ points:

$58$

$126$

The polygon has $2$ points and length $7\mathrm{.}28011$

Hints

$D=\sqrt[\phantom{2}]{(x_2-x_1{)}^2+(y_2-y_1{)}^2}$

Length$=sqrt(D).$ should be in c$++$
