On the for loop

 5      block ** (3) to be executed
 6      ** (4) after execution code block execution

The results page

Resolution:

When i is equal to 4, then, is less than 5, the implementation of (3) printed: number is 4, then i ++, i is 5 at this time, into the condition (2) is determined, is not less than 5 5. The conditions are not satisfied, terminating the code execution.

When printing out the recycle i, i is 5. In this case it will come to these results.
