Jimmy,
Yes, you are correct. This kind of feature is supported by C++ and its
generally called as RTTI (Run Time Type Idendification).
There is a small syntax problem with your code. The typeid() returns an
object of type type_info and it has a member function name() to get the
object name string.
Here is the corrected code
myClass::doSomething() {
cout << typeid(this).name();
}
hope this works for you. good luck.
regards,
Thanga
