Consider the following code. std::string* find_first(std::vector& v, char ch) { for (std::size_t i = 0; i < v.size(); ++i) { if (v[i][0] == ch) { return &v[i]; } } return nullptr;}std::vector v = { "gator", "swamp", "orange", "blue", "gold" };std::string* a = find_first(v, 'g');std::string* b = find_first(v, 'z');*a = "albert";std::string* d = find_first(v, 'g');std::cout

The program prints five numbers: [n1] then [n2] then [n3] then [n4] then [n5].

Members of a class are [dc] unless the class says otherwise; members of a struct are [ds]. When code in main reads a private member variable of an object, the result is [err]. If a class has an int member and a std::string member and no constructor initializes either one, then in a local object the int holds [iv] and the std::string holds [sv].

The last statement prints four values: [t1] then [t2] then [t3] then [t4].
