Q. Divisibility of a number and prime or not ?

THE OUTPUT WOULD BE

#include<stdio.h>
#include<conio.h>
  void main( )
  { clrscr( );
int n,i,a=0;
printf("Enter a number=");
scanf("%d",&n);
for(i=1;i<=n;i++)
{ if(n%i==0)
                 { a++;
                    printf("\nDivisible by %d",i);
                 }
}
if(a==2)
printf("\nPrime number");
getch( );

  }
