Converting a C-style string to a C++ std::string

Question

What is the best way to convert a C-style string to a C++ std::string? In the past I\'ve done it using stringstreams. Is there a better way?

Answer 1

If you mean char* to std::string, you can use the constructor.

char* a;
std::string s(a);

Or if the string s already exist, simply write this:

s=std::string(a);
