In C++ Please
![Given the class DArray below, write the definition of the member function named function54 that passes
as a parameter an STL queue of type int and an object of the class DArray. Starting with the first element in
the DArray parameter object, the function inserts elements in the calling object alternating one element
from the DArray parameter object and one element from the queue.
Example 1
DArray calling object is empty.
Queue is (front): 123
DArray parameter object is: 678
Function runs..
DArray calling object is: 61728 3
Queue is (front): 123
DArray parameter object is: 67 8
Example 2
DArray calling object is empty.
Queue is (front): 89 45 13 20 76
DArray parameter object is: 9 4 315
Function runs..
DArray calling object is: 9 89 4 45 3 13 1 20 5 76
Queue is (front): 89 45 13 20 76
DArray parameter object is: 9 4 315
Example 3
DArray calling object is empty.
Queue is (front): 6
DArray parameter object is: 45
Function runs..
DArray calling object is: 45 6
Queue is (front): 6
DArray parameter object is: 45
Parameters (in this order):
An STL queue of type int
• An object of the class DArray](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F930dba79-0d29-4e51-b7ee-c49d28417990%2F639b058f-7dca-4b31-ab4b-c144e89b69e3%2F5gdszuhj_processed.png&w=3840&q=75)

Parameters (in this order):
An STL queue of type int
• An object of the class DArray
![Return value: None
Assumption(s):
• The calling object is empty.
• The calling object has enough capacity to contain all elements inserted.
• The queue and the DArray parameter object have the same number of elements.
Restriction(s):
• If there are no elements to insert, then the function does nothing.
• The original queue that was passed as argument must be preserved (there are a couple of simple ways to
do this). This means that even if you are popping within this function all the elements in the queue, the
original queue passed by the calling function needs to stay the same.
• You may use auto only for iterators.
class DArray
{
public:
// member functions.
private:
int *a;
//will point to a dynamic array of integers
int capacity; /capacity of the array
int numOfElements; //total number of elements in the array
