Detailed Description

Formatted output class.

Formatting Integers

Formatting integers is maded using the class IntFormat that embeds the value to display and the format configuration. Then the result object is passed to the Output object that will perform the actual formatting of the output as in the example below.

void *p;
cout << io::right(io::pad('0', io::width(32, io::hex(o)))) << io::endl;
