Is it possible to count down by an amount other than one?

Answer:

Sure. The loop control variable could be decremented by any integer amount.

Live Code!

Here is some code that illustrates changing the loop control variable by an amount other than one. 

// Note: GREATER-than-or-equal operator
//

count =  ;

decrement =  ;

while ( count >= 0 )  
{
  System.out.println( "count is:" + count );
  count = count - decrement;
}
System.out.println( "Count was " + count 
    + " when it failed the test");
     

Notice each iteration of the loop subtracts a positive value (called decrement) from the loop control variable.

QUESTION 7:

Could you do exactly the same thing by adding a negative value to the loop control variable?
