![True or False:
11. If the value held at index 0 in the scores array is equal to the index of the array, we can say for certain
that the first if statement will execute.
12. We cannot say for sure what the value of i will be right after the while loop is done executing.
13. The else-if block will only execute if the value in index 0 equals 20.
14. scores[1]=printf("hello!"); would be a valid line of code.
15. In the else-if block, scores[i-2]=100; will always be updating the same index.
16. CTG currently doing DOTD on The Breakfast Club.... would be output to screen if the user enters the
numbers at the prompt in the while loop: 20, 7 and 6 (in that order)
17. We cannot say for sure how many times the for loop will execute if it starts.
18. If the for loop executes, we can say for sure what the value of the third argument in the print statement
(in the for loop) will be.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F1e1c4d29-f99c-4688-a20d-95034dea0906%2F090b372f-caa6-4fc7-8591-64e129b2dc32%2F6gn377h_processed.png&w=3840&q=75)
