Answer:
A. Database Management System
Explanation:
A Database Management System or DBMS is a set of programs that allow the DB administrator to the information extraction, storage and modification out of a database. It also provides tools to add, erase, modify or even analyze the data within the DB. Some examples of DBMS are MySQL, mongo DB, Ms SQL Server, etc.
Answer:
Yes it is possible for the following cases:-
- When the queue is full.
- When the queue is empty.
Explanation:
When the queue is full the the front and the rear references in the circular array implementation are equal because after inserting an element in the queue we increase the rear pointer.So when inserting the last element the rear pointer will be increased and it will become equal to front pointer.
When the queue is empty the front and rear pointer are equal.We remove an element from queue by deleting the element at front pointer decreasing the front pointer when there is only one element and we are deleting that element front and rear pointer will become equal after deleting that element.
<span>Assuming that the language is C++ and that the following variables exist:
bonusscores is an array of some numeric type (float, double, int, etc).
nent is an integer indicating how many elements are in bonusscores.
Also assuming that the array is 0 based, so legal subscripts range from 0 to nent-1.
// Code starts here
for(int x = 0; x < (nent-1); ++x) {
bonusscores[x] = bonusscores[x] + bonusscores[x+1];
}
// Code ends here
Thing to note, since the last element isn't modified, the range for the for loop is reduced by 1 so that every element to actually be modified is visited, but the last element isn't. And since each element after modification isn't needed for future modifications, it's safe to change them in situ.</span>
