Question

This question is a flip side of this How to efficiently copy a std::string into a vector
I typically copy the vector this way ( null terminated string )

std::string s((char*)&v[0]);

or ( if the string has already been declared ) like this

s = (char*)&v[0];

It gets the job done but perhaps there are better ways.

EDIT

C-style casts are ugly, I am told so what about this

s = reinterpret_cast<char*>(&vo[0]);

Answer 1

std::string s( &v[ 0 ] );

generates less than half the number of lines of assembly code in Visual C++ 2005 as

std::string s( v.begin(), v.end() );
