Function006

Write a general - purpose function to convert any  given year into its roman equivalent. The following table shows the roman equivalent of decimal numbers:

Decimal                            Roman	Decimal                          Roman
1                                              i 5                                              v 10                                            x 50                                            l	100                                        c 500                                        d 1000                                      m

#include <conio.h>
void main ( )
{
        int          yr;
        clrscr ( );
                  
        printf("\n\n\n\n\t\t Enter year...:"); scanf("%d", &yr);
           
        printf("\n\n\t\t ROMAN EQUIVALENT...: ");
               
        yr = roman ( yr, 1000, 'm' );                              /* Function calling */

}
