Did you install the stl? See:
http://www.digitalmars.com/faq.html#iostream

How does the program you are trying to compile look?

Open a console window and then run the program within it.

You could add this at the end of the program:

cin.get();

Or use:

#include <stdlib.h>
...
system("pause");

I assume that you define _CONSOLE

Your variable a is of type char, so "cin >> a;"
will only read one character, whether it is a
number or not. If it sould be a number it must
be a short, int, long or double, or variants
thereof.
If you type 123<enter> at the prompt, the first
character ('1') will be stored in a, the rest
(23) will be stored in c, without asking you
to hit enter.

Better use your own pause

#include <stdio.h>

void myflush ( FILE *in )
{
   int ch;

   do
     ch = fgetc ( in );
   while ( ch != EOF && ch != '\n' );

   clearerr ( in );
}

void mypause ( void )
{
   printf ( "Press [Enter] to continue . . ." );
   fflush ( stdout );
   getchar();
}

int main ( void )
{
   int number;

   // Test with an empty stream
   printf ( "Hello, world!\n" );
   mypause();

   // Leave extra input in the stream
   printf ( "Enter more than one character" );

   myflush ( stdin );
   mypause();

   return 0;
}
