   int main()
   {
       int a = 0;
       int b = 10;
       if (b = a)
          std::cout << "True \n";
       else
          std::cout << "False \n";
       return 0;
   }

   // Conditional Operator (P.103)
   #include <iostream>
   
   int main()
   {
       int i;
       for (i=1; i<=12; i++)
           std::cout << i << " - "
                << (i<8?(i%2?31:30):(i%2?30:31))
                << std::endl;
       return 0;
   }
