ciao ragazzi mi servirebbe il vostro aiuto per un programma in c++

[mattiaXD]

ciao , vorrei sapere se è possibile far "riavviare" questo programma :

#include <stdio.h>
#include <iostream>
#include <time.h>
#include <graphics.h>




using namespace std;


int X ;
int Y ;    
int c ; 
int getch(void);
int delay(void) ;                   
int main( )
{   
    
    X=1024;
    Y=768;   
    srand(time(NULL));
                                                                                      
	initwindow( X , Y , "WinBGIm" );       
	
	setfillstyle(1,RED);
	bar(X/3,Y/3,X/3+(X/3),Y/3+(X/3)); 
	
    c = (char) getch( );
    


   


    while ((c == 'v') && (c == 'V'));
    {
      c =rand()%6+1 ;    
          
      switch (c)
      {        
        case 1 :
                setfillstyle(1,WHITE);
                pieslice((X/3+(X/3))-(X/3)/2,(Y/3+(X/3))-((X/3)/2),0,360,40);
                break;
        case 2 :
                setfillstyle(1,WHITE);
                pieslice((X/3+(X/3))-(((X/3)/2))/2,(Y/3+(X/3))-((X/3)/2),0,360,40); 
                pieslice((X/3+(X/3))-(X/3)/2-(((X/3)/2))/2,(Y/3+(X/3))-((X/3)/2),0,360,40);

     }


     
     
     
    closegraph( );
    
	return( 0 );
}

p.s.: sono in c++ graphics
grazie mille
