stray '\1' ???

[dby3]

hi,this is my first post. would you help me ?
while compiling, there's msssages said that :
error : stray '\1' in program.
what is that mean ?

#include <iostream>
#include <conio.h>
#include <math.h>

using namespace std;
class PersamaanKuadrat
{
   public :
   float A, B, C;

   void input()
   {
      cout << "input nilai A:";
      cin >> A;
      cout << "input nilai B:";
      cin >> B;
      cout << "input nilai C:";
      cin >> C;
      cout << endl;
      cout << "persamaan kuadrat : "<< A << "x^2 + (" << B <<")x + ("<< C <<")";
   }

   float determinant()
   {
   	float det;
      det=sqrt((B*B)-4*A*C);
      return det;
   }

   void akar ()
   {
   	float X1, X2, det;
      det = determinant();
      X1= (-B + det)/2*A;
      X2= (-B - det)/2*A;
      cout<<"akar-akar persamaan tersebut adalah "<< X1 <<" dan "<< X2 <<endl;
   }
};

int main  ()                  

{
	PersamaanKuadrat O;
   O.input ();
   O.determinant();
   O.akar();

    getch ();
    return 0;              

}

Usually when one requires help debugging code, they display the code...

wait..
there's also SOH post in the line that makes the messages appear. what is that mean ?

It makes it easier for people to debug your code if you post it.
It would also be good to screenshot or copy/paste your error code.
