Question

1. True/False: An infinite loop occurs in a pre-test loop when a test condition can never be met.

    

2. True/False: An infinite loop occurs in a post-test loop when a test condition can never be met.

3. True/False: The following statement will generate a loop with four iterations:

                           for(count = 4; count > 0; count--)

4. True/False: The problem with a do...while loop is that the test condition cannot be a compound condition.

5. True/False: The following test condition is not valid because the toLowerCase() method cannot be included as part of a test condition:        while(toLowerCase(string)

6. True/False: If num is an integer variable, num++ and ++num can be used interchangeably in any program since the results will always be the same.

7. True/False: In the string.fromCharCode() method, string should be the name of the variable you are using in your program.

8. True/False: The string.fromCharCode() method is a static method.

9. True/False: All the ASCII characters are included in the Unicode Standard.

10. True/False: The charCodeAt() method changes the Unicode value of the character at the specified index in a string to its ASCII value. Then it returns the alphanumeric character that corresponds to the ASCII value.

Answer 1

I am answering all the questions. Let me know in comments if you have any issue in any of it

1. True

2. True

both pre and post test loops run till the condition is met, if condition is not met, then it runs infinitely

3 True

With count = 4,3,2,1

4. False, we can have compound instruction in do while loop too

5. False

6. False, one is pre increment, and one is post increment, both has different impact

7. False

8. True

9. True

10. False
