When I was compling my code this is the output I got. yes) Enter cList data (int): Add more cList data? (n = no, others = yes) Enter cList data (int): Add more cList data? (n = no, others = yes) Enter cList data (int): Add more cList data? (n = no, others = yes) Enter cList data (int): Add more cList data? (n = no, others = yes) Enter cList data (int): Add more cList data? (n = no, others = yes) Enter cList data (int): Add more cList data? (n = no, others = yes) Enter cList data (int): Add more cList data? (n = no, others = yes) Enter cList data (int): Add more cList data? (n = no, others = yes) Enter cList data (int): Add more cList data? (n = no, others = yes) Enter cList data (int): Add more cList data? (n = no, others = yes) Enter cList data  And this is what the output is supposed to looked like  Dynamic memory for 0 CNodes freed Dynamic memory for 1 PNodes freed 11  11  Dynamic memory for 1 CNodes freed Dynamic memory for 1 PNodes freed 11  12  13  14  11  12  13  14  Dynamic memory for 4 CNodes freed Dynamic memory for 1 PNodes freed 21  22  23  24  21  22  23  24  Dynamic memory for 0 CNodes freed Dynamic memory for 4 CNodes freed Dynamic memory for 2 PNodes freed 11  12  13  14  11  12  13  14  Dynamic memory for 4 CNodes freed Dynamic memory for 0 CNodes freed Dynamic memory for 2 PNodes freed 11  12  13  14  21  41  42  11  21  41  12  42  13  14  Dynamic memory for 4 CNodes freed Dynamic memory for 1 CNodes freed Dynamic memory for 0 CNodes freed Dynamic memory for 2 CNodes freed Dynamic memory for 4 PNodes freed 21  22  23  24  31  51  52  21  31  51  22  52  23  24  Dynamic memory for 0 CNodes freed Dynamic memory for 4 CNodes freed Dynamic memory for 1 CNodes freed Dynamic memory for 0 CNodes freed Dynamic memory for 2 CNodes freed Dynamic memory for 5 PNodes freed #ifndef NODES_LLOLL_H #define NODES_LLOLL_H #include    // for ostream namespace CS3358_SP2023_A5P2 {    // child node    struct CNode    {       int data;       CNode* link;    };    // parent node    struct PNode    {       CNode* data;       PNode* link;    };    // toolkit functions for LLoLL based on above node definitions    void Destroy_cList(CNode*& cListHead);    void Destroy_pList(PNode*& pListHead);    void ShowAll_DF(PNode* pListHead, std::ostream& outs);    void ShowAll_BF(PNode* pListHead, std::ostream& outs); } #endif #ifndef CN_PTR_QUEUE_H #define CN_PTR_QUEUE_H #include        // for size_t #include          // for STL stack template #include "nodes_LLoLL.h"  // for CNode namespace CS3358_SP2023_A5P2 {    class cnPtrQueue    {    public:       typedef std::size_t size_type;       cnPtrQueue();       bool empty() const;       size_type size() const; // returns # of items in queue       CNode* front();       void push(CNode* cnPtr);       void pop();    private:       std::stack inStack;       std::stack outStack;       size_type numItems;     // # of items in queue    }; } #endif #include "cnPtrQueue.h" #include using namespace std; namespace CS3358_SP2023_A5P2 {     cnPtrQueue::cnPtrQueue() : numItems(0)    {    }    bool cnPtrQueue::empty() const    {       return numItems == 0;    }    cnPtrQueue::size_type cnPtrQueue::size() const    {       return numItems;    }    CNode* cnPtrQueue::front()    {       assert(!empty());       if (outStack.empty())       {          // transfer items from inStack to outStack          while (!inStack.empty())          {             outStack.push(inStack.top());             inStack.pop();          }       }       return outStack.top();    }    void cnPtrQueue::push(CNode* cnPtr)    {       inStack.push(cnPtr);       ++numItems;    }    void cnPtrQueue::pop()    {       assert(!empty());       if (outStack.empty())       {          // transfer items from inStack to outStack          while (!inStack.empty())          {             outStack.push(inStack.top());             inStack.pop();          }       }       outStack.pop();       --numItems;    } } #include "nodes_LLoLL.h" #include "cnPtrQueue.h" #include using namespace std; namespace CS3358_SP2023_A5P2 {         // do breadth-first (level) traversal and print data    void ShowAll_BF(PNode* pListHead, ostream& outs)    {        cnPtrQueue queue;       CNode* currentNode;       queue.push(pListHead->data);       while (!queue.empty())       {          currentNode = queue.front();          queue.pop();          if (currentNode->link != 0)          {             queue.push(currentNode->link);          }          if (currentNode->data != 0)          {             outs << currentNode->data << "  ";             queue.push(currentNode->link);          }       }       outs << endl;    }     }
