A Sequence that Counts



Look at this program fragment. Click inside the program to see how it works.



    
                

            
                
int count = 0;                  // statement 1
System.out.println( count ) ;   // statement 2
count = count + 1;              // statement 3
System.out.println( count ) ;   // statement 4

            		
        

    






    



    

        Here is how the program works:
    


    
    
        
  1. Statement 1 puts 0 into count.
    2. 
        
  2. Statement 2 writes out the 0 in count.
    3. 
        
  3. Statement 3 first gets the 0 from count, 
    adds 1 to it, and puts the
    result back in count.
    4. 
        
  4. Statement 4 writes out the 1 that is now in count.
    5. 
    


    

        When the fragment runs, it writes:
    


    
0
1







Question 17:
Think of a way to write 0, 1, and 2.
