Formula to find distance between 2 3-D points

[TheInsider]

Hi,
Can someone give me a formula to find the distance between any two given 3-D points (x1, y1, z1) and (x2, y2, z2).
Thanks,

Thankyou all for looking at my thread but I think I found the solution already.

d==distance
d=sqrt( (x1-x2)*(x1-x2)+(y1-y2)*(y1-y2)+(z1-z2)*(z1-z2) )

if you make a class Point3D
friend double distance(P1,P2)
{
return sqrt( (P1.x-P2.x)*(P1.x-P2.x)+(P1.y-P2.y)*(P1.y-P2.y)+(P1.z-P2.z)*(P1.z-P2.z) )
}
