C++ moving semantics

I am new to C++ coming from C

I have seen this code and it doesn't mame sense to me how an object is returned ?

like is it a pointer or what exactly.

I have limited knowledge on value types

`std::string take(std::string&& s) {

std::string x = std::move(s);

return x;

}



int main (){

const char* b {"hello, world"};

string a = take(b);}`
