+/*There are many ways to achieve the exception handling.
+   By simple try, throw any dataType , catch it
+   By using multiple catches the throwed dataType matched catch block will exe.
+   By using catch(...){} it can exe. default it can exe any throw which is firstly throwed
+   BY throwing object use refernce of object in catch block then call the static attached error function
+   By Inherited the Exception class to your error class and and pass the constructor msg to :exceptio(msg){} then override the virtual const char*what() const {} func by adding your won comments and then return the exception::what(); of the base class.
+   By using system ddefaut inherited classes like bad_alloc , out_ofRange like
