Return 'shared_ptr' class name

What is the best way to get a 'shared_ptr' class name?

Lets say I have:

std::shared_ptr<Object> objPtr;

How can I get "Object" as a string?

The name of the class, as a string, is generally not accessible at runtime. The easiest thing to do is simply define the class name as a const member field of the object, as one of the comments suggested.

However, I caution that it is very likely that program designs that require the string name of the class are a very bad idea, and encourage you to make better use of C++'s strongly-typed nature rather than checking if the name satifies certain conditions. Unless, of course, you simply want to name of the class for debug logging.

You can do it this way:

typeid(decltype(*objPtr)).name()

Note however that the name it returns may be "mangled." How this is done, and how to "demangle" the name, is platform-dependant (aka "implementation defined").
