convert a char* to std::string

Question

I need to use an std::string to store data retrieved by fgets(). To do this I need to convert the char* return value from fgets(

Answer 1

I would like to mention a new method which uses the user defined literal s. This isn't new, but it will be more common because it was added in the C++14 Standard Library.

Largely superfluous in the general case:

string mystring = "your string here"s;

But it allows you to use auto, also with wide strings:

auto mystring = U"your UTF-32 string here"s;

And here is where it really shines:

string suffix;
cin >> suffix;
string mystring = "mystring"s + suffix;
