Given

  • v, an lvalue expression of type T or const T or an rvalue expression of type const T
  • u, an arbitrary identifier

The following expressions must be valid and have their specified effects

Expression Post-conditions
T u = v; The value of u is equivalent to the value of v.

The value of v is unchanged

T(v) The value of T(v) is equivalent to the value of v.
