       cout<<"Wrong input!!"<<endl;

       // ask again to enter again

       cout<<"Enter again:";

       // read number again

       cin>>n;

   }

   // generate random number between 1 to n

   int ran=rand()%n +1;

   // print random number

   cout<<"Random number between 1 to "<<n<<" is: "<<ran<<endl;

return 0;

}
