Hi,\
Try this:\
Class member functions can be declared as const.When this is done,that function cannot modify the object that invokes it.Also,a const object cannot invoke a non-const objects.However,a const member function can be called by either const or non-const objects.\
example:\
**class{****int some_var;****public:****unt f1() const;****};**
