Whenever We are working with Labels, Label gets Executed Even if it is not called. so for the first time i value will be incremented to 1 and then control passes to if condition there it prints i value(1).

Then label is called from if body. Now again i value is incremented to 2. So it repeats until condition in if becomes false. So we get output As 1 to 9.

Code must be as:

int i = 0, j = 0;

label:
i++;
j += i;
if (i < 10)
{
Console.WriteLine(i + " ");

goto label;

}
Console.ReadLine();

Then output will be 1 to 9.

console.write will execute as it mean to produce output, when the code gets executed the i++ inside the label will be incremented ,that is why it's from 1 to 10

The o/p is 123456789,

Why? because everytime i++ increment the i value.

And goto statement sends control.

There is nothing evil in this code.

Thanks!

It's not a while loop, it is just an if loop then how may it will repeat the loop. I think it will print only 1.

Output = 1

Here the output will be error.one main thing is the print statement itself is wrong.

It's a loop. If the condition gets true, it will go further until it gets false.

I think lable1 is considered as case and that's why it will give output.
