What are manipulators available in c?

Answer 1

C doesn't have manipulators. In C++, however, manipulators are special functions that operate upon data inserted into streams or extracted from streams. Streams are character sequences, and manipulators can be used to change the formatting parameters upon the specified stream. Manipulators can be chained within a stream insertion/extraction statement or can used as a standard function call. For example:

cout << boolalpha;

boolalpha (cout);
