<p>ACS-1903 Lab 3: printf, DecimalFormat, if Fall 2007</p><p> printf, DecimalFormatter, & if</p><p>Lab 3 is to be done outside of class and lab 3D03. You may use lab 3C13 or your own computing resources to support your work. </p><p>When you are showing the output from a program or code segment you must be precise with repect to the line produced and the number of character positions used up.</p><p>Place your answers on the lab paper itself and hand these in to your instructor (3D15) or to the ACS Office (3D11) on or before 4:00pm Monday Oct 1. There are 6 questions.</p><p>Student Identification</p><p>Student number ______</p><p>Last name ______</p><p>First name ______</p><p>Workstation user id ______</p><p>Email address ______</p><p>1.
