Without using any STL or vector, give the implementation of constructors, destructors, copy constructors, enqueue, dequeue and overloaded assignment operator of these circular buffers by making .cpp files based on the following .h files below: // file: InnerCB.h // Header file for Inner Circular Buffer. // See project description for details. // #ifndef _INNERCB_H_ #define _INNERCB_H_ class InnerCB { public: // Constructor, default size is 10. InnerCB(int n=10) ; // Copy constructor InnerCB(const InnerCB& other) ; // Destructor ~InnerCB() ; // Add item to circular buffer void enqueue(int data) ; // Remove item from circular buffer int dequeue() ; // True if no space left in buffer bool isFull() ; // True if buffer holds no items bool isEmpty() ; // return maximum number of items this buffer can hold int capacity() ; // return number of items currently held in the buffer int size() ; // overloaded assignment operator const InnerCB& operator=(const InnerCB& rhs) ; // debugging function. Prints out contents. void dump() ; // grading function used to examine private data members. // Do not implement! bool inspect (int* &buf, int &cap, int &size, int &start, int &end) ; private : int *m_buffer ; // pointer to dynamically allocate array for buffer int m_capacity ; // length of the allocated space pointed by m_buffer int m_size ; // # of items in the buffer int m_start ; // index of the first (oldest) item in the buffer int m_end ; // index of the last (newest) item in the buffer } ; #endif
