c++ catch exceptions when we use inhereted classes -

i have code this:

class a{};  class b : {};  void foo() {   throw new b; } 

here can catch exception using catch(b *e). why can not catch using catch(a *e). because private access type in inheritance?

yes that's why.

since b inherits a privately, no 1 except b aware of inheritance. b object not considered a object , cannot converted instance of a.
