Why Does The Following Code Fail? #include<iostream.> #include<string.h> Class Sample { Private :char *str ; Public : Sample ( Char *s ) { Strcpy ( Str, S ) ; } ~sample( ) { Delete Str ; } } ; Void Main( ) { Sample S1 ( "abc" ) ; }

Answer»

Here, through the destructor we are trying to deal locate memory, which has been ALLOCATED statically. To REMOVE an EXCEPTION, add following statement to the constructor.

sample ( char *s ) { str = new char[strlen(s) + 1] ; strcpy ( str, s ) ; }

Here, FIRST we have allocated memory of required size, which then would get deal LOCATED through the destructor.
