#include <stdio.h>

#include <conio.h>

#include <math.h>

#include <stdlib.h>

#define p printf

#define s scanf

int ctr,x,n,nmod;

char cont;

main()

{

do

{ clrscr();

ctr=0;

p ("Input a number: ");

s ("%d", &n);

if (n<0) p ("\nINVALID NUMBER");

else if (n==0n==1)

p ("\nNEITHER PRIME NOR COMPOSITE");

else if (n>1)

{ for (x=1; x<=n; x++)

{ nmod=n%x;

if (nmod==0) ctr+=1;

}

if (ctr==2) p ("\nPRIME");

else p ("\nCOMPOSITE");

}

p ("\n\nDo you wish to continue [Y/N]? ");

cont=getche();

}

while (cont=='Y'cont=='y');

}
