What is the output of the following statements? (Assume that all parts are independent of each other.)

a.) cout << str.size() << endl;

b.) cout << str.substr (7, 8) << endl;

string s = str.substr (ind + 4, 9);
cout << s << endl;

Explanation / Answer

please rate - thanks

a.) cout << str.size() << endl;    30     which is the length of the string

b.) cout << str.substr (7, 8) << endl;     the time      start at string index 7 and get 8 characters

c.) string: : size_type ind = str.find ('f');     the party       look for the f and starting 4 characters after
string s = str.substr (ind + 4, 9);                                              get nine characters      
cout << s << endl;

d.) cout << str.insert (11, "best ") << endl;          now is the best time for the party!    at index 11 add best   

e.) str.erase (16, 14);                                 
str.insert (16, "to study for the exam?");     now is the best to study for the exam?    starting at character
cout << str << endl;                                     16 remove 14 characters. this removes    time for the party

                                                                      then inserts at that same spot to study for the exam?
