Maybe program doesn't enter in scope of if

if (l<4)
{
        neighbors[j][i]=true;
         myfile<<j+1<<","<<i+1<<"=neighbors" << endl; 
         cout<<j+1<<","<<i+1<<"=neighbors" << endl;
}

BTW , you don't need to enter file name twice

ofstream myfile ("distances.txt");
 myfile.open("distances.txt"); // <-- this line is unecessary

Thanks. I erased the line you indicated and it worked.
