C++: Manipulators
Manipulators
Formatting data of the stream using ios member functions is a tedious job. The actions of these functions can be more easily performed using manipulators. When we use manipulators the formatting instructions are directly inserted into a stream. Manipulators can be classified into two categories, those accepting parameters (provided in 'iomanip.h') and others which do not (provided in 'iostream.h'). The following list shows all the of the manipulators.
