The For Statement

The 'for' loop is more compact than the 'while' and 'do' loops and automatically updates the loop counter at the end of each iteration. Both 'for' and 'while' loops are designed for different situations. You'll learn more about when to use each later.

6. Active For Loop


Just above the test part of a loop. This is were for loops automatically put it, and where it is
sensible to put it if you are implementing a loop with a while.

Active For Loop

Here is another example. Notice that the loop body is a block statement although there is only one statement nested inside the block. This is syntactically correct.

int count;

for ( count = 0; count < 7; count++ )
System.out.println( "count is: " + count );
System.out.println( "Done with the loop" );

Here is a JavaScript version of this loop. Try to predict what it will output:


Question 6:

Do you think that the change part of the for statement must always increment by one?
