6.12.7 The maximum and minimum representable values of a type

The keywords _Maxof and _Minof determine the maximum and minimum representable values of an integer type. Their syntax is similar to sizeof. The operand must be a parenthesized integer type. The result of these operators is an integer constant expression of the same type as the operand. For example:

_Maxof (int);    // returns '(int) INT_MAX'
_Minof (short);  // returns '(short) SHRT_MIN'
