Example

int main() {

int A2[] = {3, 1, 4, 1, 5, 9, 3};

int A3[] = {1, 2, 3, 4};

int A4[] = {1, 2, 3, 4, 5};

const int N1 = sizeof(A1) / sizeof(int);

const int N2 = sizeof(A2) / sizeof(int);

const int N3 = sizeof(A3) / sizeof(int);

const int N4 = sizeof(A4) / sizeof(int);

int C12 = lexicographical_compare_3way(A1, A1 + N1, A2, A2 + N2);

int C34 = lexicographical_compare_3way(A3, A3 + N3, A4, A4 + N4);

cout << "A1[] and A2[]: " << C12 << endl;

cout << "A3[] and A4[]: " << C34 << endl;
