Thread: problem in the context

Can anyone explain to me why this code is not working?

Code:

#include <iostream>

using namespace std;


class linkedListclass {
public:

void code(int length)  {
		
		x=length;
		if (x !=4)
			cout << "The code is short" << endl;
		else
			cout << " goooood you got it" << endl;		
}



/*  void printlist()  {
    cout << "current node is " << dvalue << endl;
    if (next != NULL)
      next->printlist();
    else
      cout << "\n\n";
  }*/

private:
  int x;

};


int main()  {
	int newvalue
	int length;
	cout << "Insert a code of 12 characters:";
	cin >> newvalue;
	length = newvalue.length();	
	
  	linkedListclass first;

  first= new linkedListclass(length);

/*  cout << "The value is " << first->getdvalue() << endl;

  first->addbehind(45);
  first->printlist();

  first->addinfront(10);
  first->printlist();*/

  return 0;
}
