FORMATTED CONSOLE INPUT/OUTPUT FUNCTONS

//formatted console input/output functions
// width() to specify the required field size
// for displaying an output value
// precision() to specify the number of digits to
// be displayed after the decimal point
// of the float value
// fill to specify a character that is used to
// fill the unused portion of the field
// setf() to specify format flags that can control the
// form of output display(such as left justi-
// fication and right justification)
//      unsetf() to clear the flags specified
//here is the basic program of defining the field width()
