description | start at 1, count upward by 2's, all values less than 10 |
sequence | 1 3 5 7 9 |
code | for ( count= 1 ; count < 10; count+=2 ) |
Here is almost the same loop as in the previous example, but now the control variable is incremented by THREE.
The expression count += 3
adds 3 to the value of count
.
int count; for ( count = 0; count <= 12; count += 3 ) { System.out.println( "count is: " + count ); } System.out.println( "\nDone with the loop.\nCount is now" + count);
Here is a version of this loop.
Try to predict the output before you run the program.
Notice that the test is now <=
.
Also, pay careful attention to the value count
has just after the loop has finished.
Complete the following for
statements so that count
has the specified values
in the loop body:
start at 0, count upward by 1's, end at 7 | for ( count = ; count < ; count++ ) |
start at 0, count upward by 2's, end at 14 | for ( count = ; count < ; count += 2 ) |
start at 1, count upward by 2's, end at 15 | for ( count = ; count < ; count += 2 ) |
