3.15.6.Loop until a random number that is greater than 20,000.

#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."
