Quick question from challenge

Question

I was ‘challenged’ by Sololearn and this was one of the questions.

Var x = 1
For (; x < 6; x+=2) {
x=x*x }

Apparently the answer is 11, but I have no idea how.

Can anyone explain?

Answer 1

Simple. Let's see the control flow of this snippet of code:

Iteration 1:
x=1, condition passes and enters the loop
x=x*x=1*1=1
x+=2 increments x by 2 and now x is 3(1+2)

Iteration 2:
x=3, condition passes and enters the loop again
x=x*x=3*3=9
x+=2 ie. x=x+2=9+2=11

Iteration 3:
x=11, condition fails and exits the loop with x holding the value 11.

I hope you got it. Feel free to ask if you get any doubts in this explanation

Answer 2

Nvm i figured it out.

The order is:
-original variable x is set (1)
-x is checked against x<6 (true)
-THEN code block is run (x=x*x or x=1x1)
-NOW is add x=x+2
