Week 09 Notes for CS 1500, Section 002 -- Spring 2001

• Check schedule
• Class starts at 11:15. I take roll at 11:25
• Announcement(s)
  • I sent out critiques on solo #2, and posted grades.
  • I also made a few updates on lab #3 and solo #1 grades that were "pending".
  • I will process the lab #4 grades ASAP -- maybe over spring break
  • I plan to do the quiz #2 grades and solo #3 grades over the break too, so all grades should be posted by the time you return.
• Some programs need to contain loops. They are a practical way to make the program repeat some instruction a large number of times.
  
  The number of times that the instruction has to be repeated could be known at the time the program is written. Example:
  
  

  
       /*  Write exactly 1000 things. */
  for (int i=1; i<=1000; i++) cout << i << "." << endl ; 

  In other cases, the number of times an instruction has to be repeated could be unknown at the time the program is written. Example:
  
  

  
          /* Read words until there are no more.  */
  #include <string>
  string theString ;
  while (cin >> theString) cout << theString.length() << endl;

• Loops are a great convenience, but it is a challenge for the programmer to "rig" the loop to execute correctly and to start and stop correctly.
