Project 25 - Controlling the Number of Decimal Places in the Output.
Controlling the Output Field Width & Alignment in the field.

Output:
A plank 10.00 feet long can be cut into 4 pieces 2.50 feet long.
A plank 10.00 feet long can be cut into 4 pieces 2.50 feet long.
EXPLAINNING IT ALL:
Alignment in the field:
-------------------------------------
Aligment to the Left -> just put a minus sign following the % sign.
Like this: %-8.2f:)
Controlling the Output Field Width
-------------------------------------
The general form of the format specifier for floating-point
values can be written like this:
%[width][.precision][modifier]f
The first output value (%8.2f) now has a field width of
eight and two decimal places after the decimal point.
The second output value (%5.0f), which is the count of the number
of pieces, has a field width of five characters and no decimal places.
The third output value (%6.2f) will be presented in a field
width of six characters with two decimal places.
There you have it! Bye! o/

/* intarg -- parse integer argument
*
* Usage: i = intarg (ptr,brk,prompt,min,max,default)
* int i,min,max,default;
* char **ptr,*brk,*prompt;
*
* Will attempt to parse an argument from the string pointed to
* by "ptr", incrementing ptr to point to the next arg. If
* an arg is found, it is converted into an integer. If there is
* no arg or the value of the arg is not within the range
* [min..max], then "getint" is called to ask the user for an
* integer value.
* "Brk" is the list of characters which may terminate an argument;
* if 0, then " " is used.
*
* HISTORY
* 18-Apr-83 Rafael Bracho (rxb) at Carnegie-Mellon University
* Changed so it beeps at the user instead of cluttering the screen.
*
* 17-Feb-83 John Schlag (jfs) at Carnegie-Mellon University
* Ported to the 68000 for the Popeye system.
*
* 20-Nov-79 Steven Shafer (sas) at Carnegie-Mellon University
* Rewritten for VAX.
