Hi santosh,

First of all I can see that you have two different variables witht he same name, String response and boolean response.

Why not assign the value that we get from console.ReadLine() to the response and then check if it is "No" ?

It will make your code look much cleaner and simplier. Make sure that you carefully read the task.

// here we declare response as empty String.

String response = "";

//then we start do while loop
do{
 // here we assign console.ReadLine(""); to response which we had declared earlier 
}
// now its time for condition
while(  ); //make sure to check if entered string is not equal to "No"

I can provide full solution but then it wouldnt be as interesting to finish figuring it out yourself :)

Have fun, Alex
