Question

WHY DOES THE ANSWER SHOW AS WRONG WHEN DATA INTEGRITY IS OK ? (Button as a component exercise)

Answer 1

Lisa, this is from Kotlin lesson, practice 30.2

Sanjay Kamath I think the only trouble is that you used capital X and the practice expects lowercase. Observe carefully the task description.

Answer 2

Tibor Santa There hadn't been any question or hint what task is, when I wrote the initial comment...

Answer 3

Tibor Santa Don't the moderators need to specify that the X should be lowercase. This cannot be assumed.

Answer 4

The moderators don't create the task :)

You can see that the "x" must be lowercase from the task:
widthxheight
or
100x150

Answer 5
