Answer:
Option B is the correct answer.
Explanation:
- In the above code, the loop will execute only one time because the loop condition is false and it is the Do-While loop and the property of the Do-while loop is to execute on a single time if the loop condition is false.
- Then the statement "x*=20;" will execute one and gives the result 200 for x variable because this statement means "x=x*20".
- SO the 200 is the answer for the X variable which is described above and it is stated from option B. Hence it is the correct option while the other is not because--
- Option A states that the value is 10 but the value is 200.
- Option C states that this is an infinite loop but the loop is executed one time.
- Option D states that the loop will not be executed but the loop is executed one time
Answer:
Sound
Explanation:
Dart is object oriented. It's sound feature helps to make codes more maintainable and readable. The sound type system means that one can never experience w state where where an expression would evaluate to a value that wouldn't match that expressions static type.
The sound system makes the code to be unambiguous. It makes the code to be easier to read as types cannot lie, also your code would be more maintainable since when a piece of code gets to be changed, you would be warned of other pieces that may have gotten broken.
