$($Geometry: distance of two points$)$

Write a program that prompts the user to enter two points $(x1,y1)$ and $(x2,y2)$ and displays their distance between them.

The formula for computing the distance is :

$sqrt((x2-x1{)}^{{?}^{{?}^{?}}}2+(y^2-y^1{)}^{{?}^{{?}^{?}}}2)$

Note that you can use Math. pow $($a$,0\mathrm{.}5)$ to compute square root of a$.$

Sample Run

Enter $x1$ and $y1$:$1\mathrm{.}5-3\mathrm{.}4$

Enter $x2$ and $y2$:$45$

The distance between the two points is

$8.764131445842194$
