The following are integer output manipulators:
boolalpha: use symbolic representation of true and false when inserting or extracting bool values. By default, bool values inserted and extracted as numeric values 1 and 0.
dec: insert or extract integer values in decimal (base 10) format.
hex: insert or extract integer values in hexadecimal (base 16) format, such as "0xFF" or simply "FF".
oct: insert or extract integer values in octal format, e.g. "077"
showbase: insert a prefix that reveals the base of an integer value.
noshowbase: reverse back to baseless integer output format.
Note: the above manipulators are sticky: they persist until another manipulator is applied.
The data type manipulators can be applied to both input and output streams.
