// Constructor IntNode::IntNode(int dataInit) { this->dataVal = dataInit; nextNodePtr = nullptr; }

// Get node value int IntNode::GetNodeData() { return this->dataVal; }

// Return index of target item int IndexOf(IntNode* headNode, int target) { /* Type your code here. */

int main() { IntNode* headNode = new IntNode(-1); IntNode* currNode; IntNode* lastNode;

// Initiaize head node lastNode = headNode;

// Add nodes to the list for (int i = 0; i InsertAfter(currNode); lastNode = currNode; }

cout

return 0; }

Given the IntNode class, define the IndexOf() function to return the index of parameter target or 1 if not found. Note: The first index after the head node is 0. Ex: If the list contains: head141912299 IndexOf(headNode, 22) returns 2. Ex: If the list contains: head -> IndexOf(headNode, 22) returns -1
