I don't understand how we got the output?!!
What's the first output in line 14? how do we calculate what's the value coming out of the loop? line 12?!

Answer is 13 15 x = 6

In line #11 - you increment the value of y for every iteration in the for loop.

In line #12 - you check whether value of x is greater than 4. If so you increment the value of y.

In line #16 - you check whether value of y is greater than 14, If so then you use the break command to exit the for loop. Once a break is executed the for loop is terminated and the value of y will be 15 outside the for loop..

Try to run below program to understand it. If you work out with a pencil and paper you will understand it better.
