#include <iostream>  
#include <cstdlib>  
using namespace std;  
  
int main()  
{  
  int i;  
  int r; 
  
 
  r = rand(); 
 
  for(i=0; r <= 20000; i++) 
    r = rand(); 
     
  
  cout << "Number is " << r << 
    ". It was generated on try " << i << "."; 
  
  return 0;  
}

Number is 26500. It was generated on try 3."
