title: cout output with visual studio and C++/OpenGL
body: <p>If I have a main function like this:</p>
  
  <pre><code>int main(int argc, char **argv) {
      glutInit(&amp;argc, argv);
      glutInitDisplayMode(GLUT_DOUBLE | GLUT_RGB);
      glutInitWindowSize (800, 600);
      glutInitWindowPosition (100, 100);
      glutCreateWindow ("A");
  
      init();
      glutIdleFunc(update);
      glutDisplayFunc(draw);
      glutReshapeFunc(resize);
      glutKeyboardFunc(keyboard);
      glutSpecialFunc(specialKeyboard);
      glutMouseFunc(mouse);
  
      cout&lt;&lt;x&lt;&lt;" "&lt;&lt;"Printed out variable x"&lt;&lt;endl;
      cout&lt;&lt;y&lt;&lt;" "&lt;&lt;"Printed out variable y"&lt;&lt;endl;
      cout&lt;&lt;z&lt;&lt;" "&lt;&lt;"Printed out variable z"&lt;&lt;endl;
      glutMainLoop();
      return 0;
  }
  </code></pre>
  
  <p>Where can I see the result of the cout calls?</p>
