- The I/O Stream Library includes a set of special functions called
- manipulators that you call by inserting or extracting the function
- name from a stream. Manipulators are more convenient than
- conventional functions because you can call them in the midst of
- a series of inputs or outputs. In this example, the manipulator
- setbase() specifies that a hexadecimal value is assigned to
- sec_val. The characters that are extracted from cin and placed in
- sec_val are treated as hexadecimal digits.
