cin.get() and omitting newline char
<p>I have a small, simple program with menu and submenus. User choose from 1-9 and hits enter. I want the code to read ONLY numbers 1-9 removing "\n" from stdin. I've tried sth like this:</p>

<pre><code>#include &lt;cstdio&gt;
#include &lt;iostream&gt;

using std::cin;
using std::cout;
using std::endl;

class cProgram
{
  private:
    char W;

  public:
    char choice(void);
    void choice(int _W);

    void showSubeMenu1(void);
    void showSubeMenu2(void);
    void showMainMenu(void);
};

char cProgram::choice()
{  return W;  };

void cProgram::choice(int _W)
{  W = _W;  };

void cProgram::showMainMenu(void)
{
  cout &lt;&lt; "MAIN MENU:" &lt;&lt; endl
       &lt;&lt; "[1] option 1" &lt;&lt; endl
       &lt;&lt; "[2] option 2" &lt;&lt; endl
       &lt;&lt; "&lt;0&gt; quit" &lt;&lt; endl
       &lt;&lt; "Your choice: ";
  choice(cin.get());
  getchar();
}

switch (choice())
{
  case '1': choice('n'); showSubeMenu1(); break;    
  case '2': choice('n'); showSubeMenu2(); break;
  case '0': break; // EXITS the program
  default: choice('n'); showMainMenu(); break;
}  

// choice('n'); sets W to neutral char (not 1,2 or 0)
</code></pre>

<p>Everything works fine, until the user hits "\n" instead of normal key. By "normal" i mean not "\n". So, when the user hits enter, it is a must to hit enter again (twice in a row). Other way the program behaves weird.</p>
