Is there a way to initialize an array with a buffer at time of declaration?

Question

Basically, I'm trying to do this:

char x[] = "hello";
char* y = new char[sizeof(x)](x); // won't work.

demo

Is there a way to do this cleanly? No comments on DO NOT USE raw arrays, or raw pointers please.

Answer 1

Just write a function.

template<typename T, size_t N>
T* new_array(T const(&arr)[N])
{
    T* p = new T[N];
    std::copy(std::begin(arr), std::end(arr), p);
    return p;
}

int main()
{
    char x[] = "hello";
    char* y = new_array(x);
}
