std::vector hasn't a sort function. Use the header <algorithm>:
#include <algorithm>
#include <vector>

std::vector<int> c;
...
std::sort(c.begin(), c.end());

but i m reading a book of "Nicolai M. Josuttis". it is highly

Is it like it was before and now removed.?
I think you may have seen use of
list<int> someList;
someList.sort()
but not vector.
It may not appear to be very unified, but the unification is via the std::sort
routine.
The headers for types like vector and sort provide overloads of std::sort where
appropriate. For a type where there's no such override std::sort uses a general
algorithm that requires random access, like indexing of a vector. But that
doesn't work for std::list, so std::list has a sort() member function
(presumably it uses merge sorting or some such that's better suited for linked
lists), and overrides std::sort to call that member function.
