[c-prog] How is Token Concatenation done here

[debasish deka]

Hello Sirs,
I have read in K&R's C Programming and was trying for implementing token 
concatenation as follows:

#define ONE        1
#define TWO        2

int main()
{
    int i;
    printf("\nEnter the number\n");
    scanf("%d",&i);
    switch(i)
    {
             case(##ONE):
             printf("\nONE");
             break;
             case(##TWO):
             printf("\nTWO");
             break;
             default:
             printf("\nDefault\n");
    }
  system("PAUSE");    
  return 0;
}

But it is giving syntax error in whichever line I am using the ##.
Can anyone help me in rectifying this error.
With Regards,
Debasish
