Why and how this piece of code is working? The compiler gives no errors or warnings.

int sum(int a,int b) {
    return a + b;
}

int main() {
    std::function<int (int,int)> pa = *****sum;
    std::cout << pa(10,12) << std::endl;
}

Thank you in advance.

@Asesh it is gcc – Sargis Khachatryan Jan 08 '21 at 12:41

@AlgirdasPreidžius It seems to be a duplicate. This problem is not at all related to `std::function` and the core of the problem is the same. – Daniel Langr Jan 08 '21 at 12:42
