  • A while loop ✔ ✖
  • B do-while loop ✔ ✖
  • C for loop ✔ ✖
  • D switch loop ✔ ✖
Correct Answer: Option C

Explanation

The for loop is most commonly used to access array elements because:

  • The number of elements in an array is usually known

  • It allows easy control of the index using initialization, condition, and increment

Example:

for (int i = 0; i < 5; i++) {
    cout << arr[i];
}

Other loops (while, do-while) can also be used, but they are less convenient for array traversal.
A switch loop cannot be used to iterate over arrays.

Correct Answer: C) for loop
