Final answer:
The correct way to assign the last element of an array with the value 99 is option A) myvector[14] = 99;. In arrays, the indexing typically starts from 0, so the last element of an array with 15 elements would have an index of 14. By assigning myvector[14] with 99, we are updating the value at that specific index to 99.
Explanation:
In arrays, indexing conventionally starts from 0. So, an array with 15 elements would have indices ranging from 0 to 14. Assigning a value to myvector[14] means targeting the element at the index position 14, which indeed represents the last element in a 15-element array. Therefore, myvector[14] = 99; accurately updates the value at the last index (index 14) of the array 'myvector' to 99. This indexing practice aligns with the zero-based numbering system commonly used in programming languages for arrays, ensuring that the assignment correctly targets and modifies the specific element that corresponds to the last position within the array.
