printing a char in graphics mode

How can I print a character in graphics mode with the
outtextxy function? I'm doing the following:

#include <graphics.h>
#include <conio.h>
#include <iostream.h>
#include <stdlib.h>
#include <ctype.h>

void main()
{

int gdriver = DETECT, gmode;
int Errcode ;
char key;

initgraph(&gdriver,&gmode,"D:\\BORLAND\\BORLANDC\\BGI\\") ;
Errcode = graphresult();
if (Errcode != grOk)
{
cout<<"Graphics Error:"<< grapherrormsg(Errcode);
exit(1);
}
setcolor(15);
key=getch();
outtextxy(10,30,key);
}

How can I print key with this function?

Thanks in advance

John's code does solve your problem and here is an alternative that I came up with.

Barry

#include <graphics.h>
#include <conio.h>
#include <iostream.h>
#include <stdlib.h>
#include <ctype.h>

struct key_word
{
unsigned int key_code;
};

struct key_bytes
{
unsigned char ascii;
unsigned char scan_code;
};

union key_fields
{
struct key_word kw;
struct key_bytes kb;
};

union key_fields key;

void main()
{

int gdriver = DETECT, gmode;
int Errcode;
int c;
char msgbuf[80];

initgraph(&gdriver, &gmode, "D:\\BORLAND\\BORLANDC\\BGI\\") ;
Errcode = graphresult();

if (Errcode != grOk)
{
cout<<"Graphics Error:"<< grapherrormsg(Errcode);
exit(1);
}

setcolor(15);

key.kw.key_code = getch();

memset(msgbuf , '\0', 80);
msgbuf[0] = key.kb.ascii;

outtextxy(10, 30, msgbuf);
} // end main()
