Loop back to the start of a program?

[millman]

#include <StdAfx.h>
#pragma hdrstop
#include <conio.h>
#include <ctype.h>
#include <iostream>

//----------------------------------------------------------------------

using namespace std;
using std::cout;
using std::endl;
using std::cin;

int main ( ) { 
int i;
int x;

std::cout << "\n Please enter an even number:";
cin >> x;
if(x%2==1)
        std::cout << "\n Number entered was not even.";
		//This is where i need the loop back to start
else
    std::cout << "\n Number entered was " <<x<< ".";  
	std::cout << "\n\n Next ten even values: ";
for (i=0; i<=8; i++) 
{
	 x=x+2;
     std::cout <<x<< " "; 
}
x=x+2;
std::cout <<x<< ".";
getch();
return 0;
}

I'll be grateful for any ideas to add to the program. Also, if it helps i'm using Microsoft Visual C++ 2010. The coding i need it to restart the program from the specified point, and if it's possible i'd like to have a y/n option. Thanks :)

I deleted my post because I thought you were asking for something else. The answer was irrelevant. Sorry for that.

before line 20 write:

while(x%2==1){

}

no problem thanks anyway alexis
And to solve the problem that when you enter an odd number into the running program it won't show the next ten alternate numbers. But i still need a code to loop back to the start. Anyway, this is the corrected program.

#include <StdAfx.h>
#pragma hdrstop
#include <conio.h>
#include <ctype.h>
#include <iostream>

//----------------------------------------------------------------------

using namespace std;
using std::cout;
using std::endl;
using std::cin;

int main ( ) { 
int i;
int x; 

std::cout << "\n Please enter an even number: ";
cin >> x;
if(x%2==1)
        std::cout << "\n Number entered was not even.";
		//This is where i need the loop back to start

if(x%2==0)   
		std::cout << "\n Number entered was " <<x<< ".";  
		
if(x%2==0)
		std::cout << "\n\n Next ten even values: ";
	
if(x%2==0)	
	for (i=0; i<=9; i++) 
	{
		x=x+2;
		std::cout <<x<< " "; 
	}
getch();
return 0;
}
