Constants ========= ProFeat allows the definition of *constants*. A constant can be defined in terms of literals or expressions including other constants. They are defined using the ``const`` keyword:: const int x = 5; const bool b = true; const double p = 0.5; Constant arrays can be defined by setting the constant to an array literal:: const int values = {1, 2, 3}; If no type is given after the ``const`` keyword, the ``int`` type is assumed.
