这个在BC45下面编译通不过

  *pscr++ = c;  

好像是提示这个有错

#include <stdio.h>
#include <conio.h>
#include <string.h>
#include <dos.h>
#include <malloc.h>
#define  DISP_MAX_X                     80
#define  DISP_BASE                  0xB800

 void PC_DispChar (char x, char y, char c, char color)
{
   char far *pscr;
   int      offset;

  offset  = (int)y * DISP_MAX_X * 2 + (int)x * 2;  /* Calculate position on the screen         */
  pscr    = (char far *)MK_FP(DISP_BASE, offset);
  *pscr++ = c;                                           /* Put character in video RAM               */
  *pscr  = color;                                       /* Put video attribute in video RAM         */
}
main()
{ PC_DispChar(20,14,50,12);
return 0;
}

/* MK_FP example */

#include <stdio.h>
#include <conio.h>
#include <string.h>
#include <dos.h>
#include <malloc.h>

main()
{

  char *str = "hello\n";
  char far *farstr;

  printf ("the address pointed to by str is %04X:%04X\n",
    FP_SEG(str), FP_OFF(str));
  farstr = (char far *)MK_FP( FP_SEG(str),  FP_OFF(str));

  printf ("the string pointed by far pointer is %s\n", farstr);
  return 0;
}
