Chapter Review 
=========================

- Note that the course policy is that you should not use generative AI 
  without authorization. If you are suspected to have used generative AI 
  and not able to explain/reproduce your work when requested, all your 
  **related assignments throughout the semester will be regraded as 0.**

- Prepare this assignment using a Word document.
- Number and write answers under each question.
- Paste code screenshots when required.

.. note:: 
    You are encourage to keep your test code in the project. To do that:

    - Create a dotnet console app project (:ref:`create-project`), if you 
      have not done that, in your *USERNAME*/workspace/introcscs directory; called it 
      **Ch05ForLoop**. 
    - Place your test code in methods to be called from the Main method. Name your 
      methods properly. 


   
#.  When you have nested ``for`` loops, and you reach the bottom of the *body* of the
    *inner* loop, where does execution go next?


#.  What happens when you omit the condition in a ``for`` loop? 
    
    Explain and try it out in csharprepl or VS Code and paste the results here. 


#.  In the heading of a ``for`` loop, how do you initialize or update
    several variables?

    
#.  Rewrite ::
   
        num /= 2;
        
    equivalently without the operand ``/=``.
    
#.  Rewrite ::

       bigName = bigName - 10;
       
    with a statement that only includes ``bigName`` once.
    

#.  Distinguish the effects of these two statements::

       x-=2;
       
       x=-2;
       
       
#.  What is printed?  ::

        Console.WriteLine("12345678");
        for( int p = 1; p < 6; p++) {
            string formatStr = "{0:F" + p + "}";
            Console.WriteLine(formatStr, 1.2345678);
        }

    Explain, then paste here the screenshot of the results of you testing it in csharprepl or VS Code. 


#.  What is printed?  (Just ",4" has been inserted.) ::

        Console.WriteLine("12345678");
        for( int p = 1; p < 6; p++) {
            string formatStr = "{0,4:F" + p + "}";
            Console.WriteLine(formatStr, 1.2345678);
        }
    
    Explain, then paste here the screenshot of the results of you testing it in csharprepl or VS Code. 

        
#.  What is printed?  ::

        Console.WriteLine("123456");
        for( int w = 6; w >= -6; w -= 4) {
            string formatStr = "{0," + w + "}|";
            Console.WriteLine(formatStr, "here");
        }

    Explain, then paste here the screenshot of the results of you testing it in csharprepl or VS Code. 


    
#.  Even if you want to process every element of a sequence, what would keep
    you from using a ``foreach`` loop?
    


.. #.  May you legally omit the initialization part of a ``for`` loop?
