       {
          printf("its a tie: Your choice = %d, CPU = %d\n", gVar, CPU);
       }
       else if(gVar < CPU)
       {
         if(gVar==0 && CPU == 2 )
         {
           printf("You Won: Your choice = %d, CPU = %d\n", gVar, CPU);
         }
         else

       {
          if(CPU == 0 && gVar == 2)
          {
             printf("CPU Won: Your Choince = %d, CPU =%d\n", gVar, CPU);
          }
          else
