Explanation / Answer

// string constructor #include #include using namespace std; int main () { string s0 ("Initial string"); // constructors used in the same order as described above: string s1; string s2 (s0); string s3 (s0, 8, 3); string s4 ("A character sequence", 6); string s5 ("Another character sequence"); string s6 (10, 'x'); string s7a (10, 42); string s7b (s0.begin(), s0.begin()+7); cout
