<span>When studying an information system, illustrations of actual documents should be collected using a process called sampling. Correct answer: D
</span>This process systematically selects representative elements of a population with the goal to get representative and useful information about the population as a whole and it is useful when <span>data sets that are too large to efficiently analyze in full.</span>
Answer:
A.O(1)
Explanation:
In the implementation of queue by using linked chain the performance of the enqueue operation is O(1).We have to maintain two pointers one head and the other tailand for enqueue operation we have to insert element to the next of the tail and then make that element tail.Which takes O(1) time.
Answer:
class studentType: public personType
{
public:
