Data hiding is concept of making your data private i.e. only accesible within the class member functions.

e.g
       class check
       {

           private:
/* This is private data cant access outside the class */
            int i ;
           public:
             int j;
         };

main()
{
  Check c1;

  c1.i=0; //// Error
   c1.j=0; ///works fine


}

       HTH
