III. Data structure: Here is the pseudocode. Now need the implementation in C++ ******************************** - listNode class

friend of hashTable - (string) firstName - (string) lastName - (listNode *) next methods: - constructor (firstName, lastName) //create a node with given data - printNode (node) // use the format: (this node's firstName, this nodes lastName, next nodes firstName ) // see example given in the above.

- hashTable class - (char) op // either '+' or '- or '?' - (int) bucketSize // via argv[2] - (listNode *) hashTable [bucketSize] method: - createHashTable (...) // The method dynamically allocates hashTable [], size of bucketSize, //where each entry point to a dummy node: (dummyfirst, dummylast, null)
