It increases count by one.


Incrementing count





    

    

    

        

            

                

            

        

    















    







    
If the answer is not clear, remember the two steps of an assignment statement:

    
    
        
  • first evaluate the expression on the right of the equal sign,
    • 
        
  • second put the value in whatever variables on the left.
    • 
    

    
Say that count is 2. When the above statement executes, first the expression count + 1 is evaluated, resulting in 3. Second the 3 is put in count.






Question 3:
What does this statement do:
    count = count + 2;
