Two strings, code1 and code2, are read from input as two states' codes. headObj has the default value of "code". Create a new node firstState with string code1 and insert firstState after headObj. Then, create a second node secondState with string code2 and insert secondState after firstState. Ex: If the input is MA IA, then the output is: code MA IA #include using namespace std; class StateNode { public: StateNode(string codeInit = "", StateNode* nextLoc = nullptr); void InsertAfter(StateNode* nodeLoc); StateNode* GetNext(); void PrintNodeData(); private: string codeVal; StateNode* nextNodePtr; }; StateNode::StateNode(string codeInit, StateNode* nextLoc) { this->codeVal = codeInit; this->nextNodePtr = nextLoc; } void StateNode::InsertAfter(StateNode* nodeLoc) { StateNode* tmpNext = nullptr; tmpNext = this->nextNodePtr; this->nextNodePtr = nodeLoc; nodeLoc->nextNodePtr = tmpNext; } StateNode* StateNode::GetNext() { return this->nextNodePtr; } void StateNode::PrintNodeData() { cout << this->codeVal << endl; } int main() { StateNode* headObj = nullptr; StateNode* firstState = nullptr; StateNode* secondState = nullptr; StateNode* currState = nullptr; string code1; string code2; cin >> code1; cin >> code2; headObj = new StateNode("code"); /* THE NEEDED CODE GOES HERE. THE REST OF THE CODE IS FINE. */ currState = headObj; while (currState != nullptr) { currState->PrintNodeData(); currState = currState->GetNext(); } return 0;

C++ CODING PROBLEM WHERE I NEED CODE TO CREATE A LINKED LIST

(I also put a screen shot of the problem below. 

Two strings, code1 and code2, are read from input as two states' codes.

headObj has the default value of "code".

Create a new node firstState with string code1 and insert firstState after headObj.

Then, create a second node secondState with string code2 and insert secondState after firstState.

Ex: If the input is MA IA, then the output is:

code

MA

IA

#include <iostream>
using namespace std;

class StateNode {
   public:
      StateNode(string codeInit = "", StateNode* nextLoc = nullptr);
      void InsertAfter(StateNode* nodeLoc);
      StateNode* GetNext();
      void PrintNodeData();
   private:
      string codeVal;
      StateNode* nextNodePtr;
};

StateNode::StateNode(string codeInit, StateNode* nextLoc) {
   this->codeVal = codeInit;
   this->nextNodePtr = nextLoc;
}

void StateNode::InsertAfter(StateNode* nodeLoc) {
   StateNode* tmpNext = nullptr;

   tmpNext = this->nextNodePtr;
   this->nextNodePtr = nodeLoc;
   nodeLoc->nextNodePtr = tmpNext;
}

StateNode* StateNode::GetNext() {
   return this->nextNodePtr;
}

void StateNode::PrintNodeData() {
   cout << this->codeVal << endl;
}

int main() {
   StateNode* headObj = nullptr;
   StateNode* firstState = nullptr;
   StateNode* secondState = nullptr;
   StateNode* currState = nullptr;
   string code1;
   string code2;

   cin >> code1;
   cin >> code2;

   headObj = new StateNode("code");
   
   /* THE NEEDED CODE GOES HERE. THE REST OF THE CODE IS FINE.  */

   currState = headObj;
   while (currState != nullptr) {
      currState->PrintNodeData();
      currState = currState->GetNext();
   }

   return 0;
