#include <boost/troll.hpp>
//...
boost::troll::detector detector(Thread_Opener);
if(detector.is_troll())
{
    boost::troll::monster_slayer slayer;
    slayer.kill(Thread_Opener);
}
else
{
    std::cout << "The detector is broken\n";
}

Probiers mal so:

#include <boost/troll.hpp>
//...
boost::troll::detector detector(Thread_Opener);
if(detector.is_troll())
{
    boost::troll::monster_slayer slayer;
    slayer.kill(Thread_Opener);
}
else
{
    std::cout << "The detector is broken\n";
}

vielen dank für die antwort
ich habe schon selbst versucht einen einfach code zu schreiben :

//Node class

#include<vector>

struct Point // the location of the pixel with the its value
{
    int x;
    int y;
    int value;
};

class Node // a node in the tree which contains many of pixels ,that  //the  difference among its value less than specified value(threshold)
{
public:
    Node(int x, int y, int w, int h);
    int posX;
    int posY;
    int width;
    int height;
    bool leaf;
    Node* child[4];
    std::vector<Point> pointArray;
};

// CONSTRUCTOR
Node::Node(int x, int y, int w, int h)
{
    posX = x;
    posY = y;
    width    = w;
    height    = h;
    leaf=false;
}

und nun möchte encoding diesen quadtree
