Yes true string is not a datatype in C++ but it is implemented through Standard Template Library. And the string class has dynamic memory allocation.
eg:-
string str;
cin>>str;

string str gets dynamically allocated storage and that storage size is not permanent and can be modifies later.

after:
what happens behind screen is actualy:
string str = new char[strlen(str) + 1];
when you take input of the string str its size is calculated and you get the desired meomry.
