Type Modifiers          Keywords That Modify Data Types

    Type modifiers are keywords that can be used to prefix a data type in
    a declaration or cast. They modify the type by changing its storage
    size (e.g. short and long) or the way in which it is interpreted
    (e.g. signed and unsigned.) They may even place certain restrictions
    on the type (e.g. const and volatile.)

      Notes:    As shown below, type modifiers may be combined in the
                same declaration. There are two restrictions, however: A
                declaration may not include both long and short, or both
                signed and unsigned. All other combinations are valid.

                Type modifiers may be specified in any order.

     unsigned long int uli;
     signed short int ssi; const int ci;
     const unsigned short int cusi;
     volatile short int vsi;
