PRIME NUMBER IN C++

PRIME NUMBER:-
prime number is a whole number greater than 1,
 whose only two whole-numberfactors are 1 and itself. The first few prime numbers are 2, 3, 5, 7, 11, 13, 17, 19, 23, and 29. As we proceed in the set of natural numbers N = {1, 2, 3, ...}, the primes become less and less frequent in general.


E.G:-


#include<iostream.h>
#include<conio.h>;

void main()
{
  int n, i, j=0;
  cout << "Enter a positive integer: ";
  cin >> n;
  for(i=2; i<=n/2; i++)
  {
      if(n%i==0)
      {
          j=1;
          break;
      }
  }
  if (j==0)
      cout << "This is your  prime number";
  else
      cout << "This is not a prime number";
 getch();
}
IN  this CODE NOT ANY COMPILE AND RUN TIME ERROR this already checked in turboc++
