$2\mathrm{.}15$ The distance between two points $(x_1,y_1,z_1)$ and $(x_2,y_2,z_2)$ in a three$-$

dimensional Cartesian coordinate system is given by the equation

$d=\sqrt[\phantom{2}]{(x_1-x_2{)}^2+(y_1-y_2{)}^2+(z_1-z_2{)}^2}$

Write a program to calculate the distance between any two points $(x_1,y_1,z_1)$ and

$(x_2,y_2,z_2)$ specified by the user. Use good programming practices in your program.

Use the program to calculate the distance between the points $(-3,2,5)$ and $(3,-6,-5).$
