Don't understand the Quiz

the question : 

int counter = 0;

while(counter < 5)
{    
    counter += 1;

    if(counter == 2)
    {
        break;
    }
}

Console.WriteLine(counter);

i want to double confirm What's mean (Counter ==2)? And the answer should be counter = 1?

thank you

Hello Issac,

The counter variable will have a value of 2 after the while loop. Let's see why.

Counter starts at 0, so the first iteration of the loop will increment counter to 1 and the if condition will be false, so the loop continues to the next iteration.

Next iteration, the counter is incremented again, making the counter 2. Immediately after counter is incremented, the if condition is true and the while loop is exited. The result: the value of counter is 2.

I hope this helps.

Happy Coding :)
