Understand this challenge

Question

Hi I’ve been trying to understand this challenge.
The output is 26 but I am figuring out how it got to that number.

int x=1;
for(; x<6; x++)
x*=x;
System.out.printf(“%d”,x)

Any help would be appreciated.

Answer 1

//same x is increasing by mulplication & by addition of 1
loop 1)1×1 =1 [1 <6]
then incremented by 1
loop2)2×2 =4 [2 <6]
then incremented by 1
loop3)5×5 [5 <6]
then incremented by 1
//condition becomes false [26 is not <6] & loop stops ... 26 printed

//@Frost,Tom
//hope it helps ☺👍

Answer 2

@Frost
It has some problem. No semicolon.😊😉
System.out.printf(“%d”,x);

Answer 3

x=x*x will change everytime x changes/increases
1*1=> x=1
2*2=> x=4

5*5 => x=25 and then as x cannot be 6 it will go out of the loop after incrementing i.e x++ of 25 will give 26

Answer 4

First Loop:  x = 1
x*=x (same as x = x*x) = 1*1 = 1
x++ (increments by one) = 1+1 = 2

Second Loop: x = 2
x*=x = 2*2 = 4
x++ = 4+1 = 5

Third Loop: x = 5
x*=x = 5*5 = 25
x++ = 25 + 1 = 26

Exits Loop as x = 26  which is not < 6 (the condition is false)

Ahh. I understand it now. Thank you guys for the quick response. Amazing.
