Question

If you need to write a do-while loop that will ask the user to enter a number between 2 and 5 inclusive, and will keep asking until the user enters a correct number, what is the loop condition? (2 > number || number > 5) (2<5 number && number > 5) (2 <= number && number <= 5)

Answer 1

Answer: (2 > number || number > 5)

Step-by-step explanation:

The do-while loop need to work until the user enters a correct number. In this case the number need to be between 2 and 5 inclusive.

On the opposite, if the user enters a number between 2 and 5 inclusive, he will leave the do-while loop.

Here is how it works : Once the user enters a number, the do-while loop will check this number.

If the number is NOT between 2 and 5 inclusive, the do-while loop will ask again the user to enter a number.

If the number is between 2 and 5 inclusive, the loop stop working.

So the do-while loop need to check if the number IS NOT between 2 and 5 inclusive.

If it is not between 2 and 5 inclusive, it could be :

Smaller than 2 : number < 2

Or greater than 5 = number > 5

The "or" condition is written by the symbols "||".

The loop condition is (2 > number || number > 5).
