Hello I start studying c++ and I'm trying to learn what data type is something that starts with a L, like
auto something = L"Monday";
What data type is auto?
And how do I convert a std::string to this data type?
std::string my_string = "Hello World"; to ? something = L"Hello World"
auto is not a data-type. It is a placeholder that gets deduced depending on the initializer used.
In your case, the initializer is a wide string-literal of type const wchar_t[size], which decays to const wchar_t* when used to initialize the variable.
A wide string can be stored in a std::wstring.
How to convert a std::string (a narrow string) to a wide string depends on the source's character encoding.
Anyway, there are many others who asked that too:
