Can you explain how this code works?

Question

for(var x=1; x<5; x+=2){
x=x*x;}
alert(x)

how returns 11?

Answer 1

initializing x to 1
x becomes 1
checking 1<5? true
x = x*x
x becomes 1*1 ie 1
x +=2
x become 3
checking 3<5? true
x = x*x
x become 9
x+=2
x become 11
checking 11<5 false
exit loop
x is 11

Answer 2

thank you!

Answer 3

First of all x is initialize with value 1.

Condition holds true and x = 1*1 = 1.

Now x is incremented by 2 i.e x = 3.

Condition still holds true and x = 3*3 = 9.

Now again x is incremented by 2 i.e x = 11.

Now condition => false.

Finally it alerts x's value i.e 11.

Hope this helps ☺️☺️.

Answer 4

Base upon the condition of the loop it will multiplied x by x and than it increment x by 2 and check if x is less than 5 ,
first
loops command : multiply x by x
x= 1*1=1
loop question: is x less than 5 , answer yes it is ,than increment x by 2
by the way the word increment mean add 2 to the value of x ,
x=1+2 = 3;
loop: command : multiply x by x it self;
x= 3*3=9
loop always increment before checking so
x+=2 =11;
loop question is x lesser than 5 no false ,so break and out put x if asked for
now when we request the value of x , x=11;
I hope this help you

Answer 5

After running loop's code , value is always incremented or decremented and than condition is checked.

If condition holds true code is executed else exit the loop.

Answer 7

for any programming language this will flag error.. Cr: not found x

it might be javascript😂😂

Answer 8

Initialize x to 1
X=x*x return 1
Then x=x+2 so x become 3
And x*x=3*3=9
Then we ajoute 2 to x it become 11 and 11>5 so we exit from the boucle

Answer 9

Could you please remove the java tag and put javascript instead? So that people who are looking for java questions won't find your question.
Thank you
