Using the initialization code shown below, which one of the following C expressions is NOT guaranteed to be true when evaluated?

• x == (unsigned) x


• x == (int) (unsigned) x


• x == (int)(float) x

Elaborate on why each line of code would be sure to be evaluated to true while 1 is not always guaranteed to be true (under which/what circumstances).
