Given the following definition of a queue data structure implemented using a circular array. Assume all methods but the isFull function have been properly implemented.

Help please the function isFull is the only one I need help with it is supposed to return true if the array is full and false if it is not full I Just need to know the code to check if it is full or not help please this is from the study guideC++
Transcribed Image Text:Given the following definition of a queue data structure implemented using a

class CircularArrayQueue: public Queue {
private:
int* arr_
//an array to hold all elements of the queue
unsigned capacity_; //the maximum number of slots in the array
int front; //index for the oldest, front element in the queue
//index for the newest, rear elements in the queue
int rear_;
public:
CircularArray Queue (unsigned n) ;
~CircularArrayQueue ();
bool isFull() const;
void push (const string& val);
void pop();
In the following space, implement the is Full member function to return true if the queue is full
and cannot take any new element. The function shall return false otherwise. The implementation
must be of an O(1) time complexity. No loop is allowed.
