How to initialize the dynamic array of chars with a string literal in C++?

Question

I want to do the following:

std::unique_ptr buffer = new char[ /* ... */ ] { \"/tmp/file-XXXXXX\" };

Obviously, it doesn\'t work

Answer 1

Since you requested a dynamic array and not wanting to count the length, that rules out std::array. What you're asking for is really just std::string - it's dynamic (if need be), and initializes just fine from a char* without counting the length. Internally, it stores the string in a flat array, so you can use it as such, via the c_str() call.
