No, I get these error messages:
dynamic.C:1: `typeinfo' was not declared in this scope
dynamic.C:3: syntax error before `{' token
dynamic.C:5: parse error before `{' token
dynamic.C: In function `int main()':
dynamic.C:8: invalid use of undefined type `class B'
dynamic.C:5: forward declaration of `class B'
dynamic.C:9: `A' undeclared (first use this function)
dynamic.C:9: (Each undeclared identifier is reported only once for each
function it appears in.)
dynamic.C:9: `a' undeclared (first use this function)
dynamic.C:9: parse error before `*' token
dynamic.C:10: must #include <typeinfo> before using typeid
dynamic.C:8: warning: unused variable `B*b'
