Value and size of an uninitialized std::string variable in c++

Question

If a string is defined like this

std::string name;

What will be the value of the uninitialized string \"name\" and what size it would be?

Answer 1

The Standard (C++11, §21.4.2/1) describes the results of default-constructing a std::basic_string (of which std::string is a specialization) as follows:

[...] an object of class basic_string. The postconditions [...] are indicated in Table 63.

And Table 63 says:

data() a non-null pointer that is copyable and can have 0 added to it
size() 0
capacity() an unspecified value
