I need explanation how can I implement this header code on cpp file?

private Il Note we did not need to make this a template // since this struct is part of a template class. struct Node { Node* next; int len; T values[ARRAY_SIZE] Node* head; Node* tail; // iterator Node* iterNode; // What node are were currently on? int arrPos; // Within the node, what element are we looking at? int listLen; // Total elements int numChunks; // Total chunksodes #include "ChunkList.cpp" #endif //CHUNKLIST CHUNKLIST H s Chunklist private Il Note we did not need to make this a template // since this struct is part of a template class. struct Node { Node* next; int len; T values[ARRAY_SIZE] Node* head; Node* tail; // iterator Node* iterNode; // What node are were currently on? int arrPos; // Within the node, what element are we looking at? int listLen; // Total elements int numChunks; // Total chunksodes #include "ChunkList.cpp" #endif //CHUNKLIST CHUNKLIST H s Chunklist
