title: How detect spacebar?
body: <p>I have a program in c++ where I have to detect spacebar, how can I do? I see that I need the function <code>getch()</code>, but in my program I haven´t <code>conio.h</code>. Exist other solution?</p>
  
  <p>With <code>getchar</code> I need press <code>intro</code>, exist other form that I press only spacebar?</p>
  
  <p>For example, can I introduce a <code>intro</code> without press <code>intro</code>???</p>
