Question

List = [10, 5, 15];

for (var i = 0; ; i++){
(list[i]);
}
Which of the following will NOT result in an error if placed where the program reads and the program is run?

A) i < list[ ]
B) i <
C) i < list[0]
D) i < list[1]

Answer 1

Option D) i < list[1] will not result in an error in the given program because it is a valid comparison preventing out-of-bound errors, unlike the other options which are either syntactically incorrect or would lead to runtime errors due to out-of-bounds access.

Step-by-step explanation:

The answer to the student's question about which condition will NOT result in an error if placed in the provided program is option D) i < list[1]. This condition checks if the variable i is less than the second element of the list, which is 5 in this case. Since this is a valid comparison, the condition will correctly prevent the program from running into an error caused by an out-of-bounds index.

The other options will cause errors as follows: Option A) i < list[] is syntactically incorrect because you need an index to access an array's element. Option B) i < is incomplete and causes a syntax error. Option C) i < list[0] would not cause a syntax error, but since list[0] is the value 10, it would allow the loop to attempt to access list[10], which is out of bounds, leading to a runtime error.
