Formatting (manipulators)

• Practice : Prata manip.cpp

• See table 17.3, page 891 for some standard ones.

• Just put them in the output stream.

  • cout << hex << 123 << endl;
  • // outputs 7b

• Or call them.

  • cout.fill('$'); cout.width(5); cout << 123 << endl;
  • // outputs $$123

• They change a state and persist until they are changed.

• #include <iomanip>
