Chapter 6.4, Problem 2E

(Practice) Write a C++ program that accepts the rectangular coordinates of two points $\left(x_1,y_1\right)and\left(x_2,y_2\right),$ calculates the distance of each point from the origin, and calculates the distance between the two points. The distance, d, between two points is given by this formula:

$d=\sqrt{{(x_2-x_1)}^2+{(y_2-y_1)}^2}$
