[Dev-C++] Escape key sequence

[<and...@su...>]

Dear Users,

   Concerning the Esc escape sequence on the following while, let me report
my exact problem:

In C, this works:

#include <stdio.h>
#include <stdlib.h>

int main()
{
   char tecla='x';

   do
   {
      printf(" the key is-->%c\n", tecla);
   }while((tecla = getche())!= 27);

   system("pause");
   return 0;
}

I´ve changed the getchar by the getche() function and It worked.

But, with the following code:
#include <iostream>
#include <cstdlib>
using std::cout;
using std::endl;
using std::cin;
int main()
{
   char tecla='x';

   do
   {
      cout << " not escaped yet!!! " << endl;
   }while(tecla = cin.get()!= 27);
   system("pause");
   return 0;
}
--> The behavior of cin.get() seems to me equivalent to getchar(). And the
getchar() function stores on the 1st time the caracter and on the second the
'\n'. And, it doesn´t escape when
I press the Esc key, ok?
--> What I need is way to write this second program working the same way as
its previous above.

Andre
