Could someone please explain to me why the answer is 2?

It all has to do with the counter variable. Through every iteration of the loop, the counter variable increments by one and tests the condition of if(counter == 2) and while(counter < 5). Once it reaches 2, the code breaks out of the loop. The code doesn't get all the way to 4 because the if statement breaks the loop. The "==" is the comparison operator to see if two values are the same, but don't get double equals mixed up with "=", as that's for setting values. Hope this helps!

Think about how the execution will behave when the code is run, in more of plain english steps the code reads like this:

create 'counter' variable and set it to 0

loop through the while block while 'counter' is less than 5

the loop increments the counter

after the increment, check if 'counter' is equal to 2, if so break out of the loop

print counter after loop

Like this it should become clear that no matter what counter is, it will only ever break out of the loop to get to the WriteLine statement when counter == 2.

Hope this helps! Happy coding!

Is counter = 5? No, keep updating the counter aka +1, is counter = 5 ( is 1 = 5 ), no keep updating counter aka +1, now counter is equal to 2. Here you have a second condition: if counter is equal to 2, well yea it is, than break aka stop and get out of the while loop :) That is it
