The distance between two points sx$1$

$,$ y$1$

$,$ z$1$

d and sx$2$

$,$ y$2$

$,$ z$2$

d in a three$-$dimensional

Cartesian coordinate system is given by the equation

d $5$sx$12$ x$2$d

$21$ sy$12$ y$2$d

$21$ sz$12$ z$2$d

$2(2\mathrm{.}47)$

Write a program to calculate the distance between any two points sx$1$

$,$ y$1$

$,$ z$1$

d and

sx$2$

$,$ y$2$

$,$ z$2$

d specified by the user. Use good programming practices in your pro$-$

gram. Use the program to calculate the distance between the points s$23,2,5$d

and s$3,26,25$d$.$
