No.
The change part can be complicated, if you want. It is best to keep it small and understandable. Here is almost the same loop as in the previous example, but now the control variable is incremented by two.
The expression count += 2
adds the value 2 to the variable count
.
(For more details on this see chapter 31.)
Try to predict the output before you run the program.
The change to count
is done at the bottom
of the loop body.
This means that the last value that count
gets is the first one that
fails the test count < 7
.
This is the value count
will have just outside the loop body.
Questions like this are common on midterm and final examinations. If you rush, you are likely to get them wrong. But with careful thought they are easy enough.
int count; for ( count = 0; count < 7; count += 2 ) { System.out.println( "count is: " + count ); } System.out.println( "\nDone with the loop.\nCount is now" + count);
Read the description, and then fill in the blanks of the sequence. Then fill in the blanks of the loop that creates the same sequence.
