Getting substring of wchar_t[]

Question

I have:

wchar_t str[32];

I want to get a new substring of it, from place 0 to 5. How can I do it?

Answer 1

std::basic_string does have the constructor you're looking for:

constexpr basic_string( const CharT* s,
                        size_type count,
                        const Allocator& alloc = Allocator() );

So you may do:

std::wstring substr{str, 5};
