Consider the following statement:

string str = "Now is the time for the party!";

State the output of following statements? (Consider that all parts are independent of each other.)

a) cout << str.size() << endl;
b) cout << str.substr(7, 8) << endl;
c) string::size_type ind = str.find('f');
string s = str.substr(ind + 4, 9);
cout << s << endl;
d) cout << str.insert(11, "best ") << endl;
e) str.erase(16, 14);
str.insert(16, "to study for the exam?");
cout << str << endl;
