Let suppose
int a, b, c, d, e; a = b = c = d = e = 42;This can be interpreted by the complier as:

If a class A declares itself a friend of class B and a class B declares itself a friend of class C then
► Class A is also a friend of class C.
► Class B is also a friend of class A.
► Class A is also a friend of class C if A declares C as its friend.
