odd and even integers

how can i get the sum of odd and even integers by using only one while loop?

 

Code:

#include<stdio.h>
#include<conio.h>
int main()
{
int n,even=0,odd=0;
clrscr();
printf("Enter the numbers(0 to exit)");
while(1)
   {
    scanf("%d",&n);
    if(n==0)
        break;
    if(n%2==0)
	even+=n;
    else
	 odd+=n;
   }
printf("Sum of odd numbers = %d\n",odd);
printf("Sum of even numbers = %d\n",even);
getch();
return 0;
}
