First, lets look at what the continue keyword does. The continue keyword stops the current iteration of a loop and returns control at the begining of the loop.

Now lets walk through the loop execution.

First iteration. x = 1
1< 5 so we hit the continue statement

Second iteration x = x + 3 = 4
4<5 so again we hit the continute statement

Third iteration x = x + 3 = 7
7>5 so we print x*x which = 49

Fourth iteration x = x + 3 = 10
10>5 so we print x*x which = 100

Fifth iteration x = x + 3 = 13 (13 > 10 so the loop terminates)
