  	hex - to print numbers in hexadecimal base
  
  	oct - to print numbers in octal base
  
  	dec - to print numbers in decimal base
  
  	dec is active by default for input output stream
  
  	these are the memebers of iomanip headers
  
  	sometimes we need to include the header like this,
  
  										#include <iomanip>
  
  	sometimes it work without including the header iomanip
  
  	In update compilers don't need to include iomanip
