43. A nurse is preparing to administer 400 mL of 0.9% sodium chloride IV over 8 hr. The drop factor of the manual IV tubing is 60 gtt/mL. The nurse should set the manual IV infusion to deliver how many gtts/min? (Round to the nearest whole number. Numerical answer only). __________ 

With that one line deleted, the program prints [out].

Vehicle.h class Vehicle { std::string make; int year;public: Vehicle(); // (1) Vehicle(std::string make, int year); // (2)};

Part E — Code Review (8 points)The code below compiles without warnings, and each function is supposed to meet the specification in its comment. It does not: the three functions contain several defects. review.cpp class Scoreboard { std::vector scores; std::size_t capacity;public: Scoreboard(std::size_t capacity) : capacity(capacity) {} // Spec: Add score unless the board already holds `capacity` scores. // Return true if it was added. bool Add(int score) { if (scores.size() > capacity) return false; // Line 1 scores.push_back(score); // Line 2 return true; } // Spec: Return the average of the scores, or 0 if there are none. // The average of 1 and 2 is 1.5. double Average() { int sum = 0; // Line 3 for (int s : scores) sum += s; return sum / scores.size(); // Line 4 }};// Spec: Read every score in the file named by the program’s first command// line argument into the caller’s board. Return how many scores were// read, or -1 if the file could not be opened.int load(Scoreboard board, char* argv[]) { // Line 5 std::ifstream fin(argv[0]); // Line 6 int score; int n = 0; while (fin) { // Line 7 fin >> score; board.Add(score); n++; // Line 8 } return n;}

The last line prints three values: [w] then [k] then [t].

Which constructor runs for each line?Vehicle a; runs [r1]Vehicle b(“Rust Bucket”, 2015); runs [r2]std::vector v(3); runs [r3]Vehicle d(); runs [r4]

Consider the following code. class Ticket { static int issued; int id;public: Ticket() { issued += 1; id = issued; } int getId() { return id; } static int count() { return issued; }};int Ticket::issued = 0;int nextCode() { static int code = 100; code += 5; return code;}int main() { std::cout

sum.cpp #include #include int main(int argc, char* argv[]) { int sum = 0; for (int i = 0; i < argc; ++i) { sum += std::stoi(argv[i]); } std::cout

The parameters x and y have [dur] storage duration. At Line L, ptr is [kind] pointer, and dereferencing it is [what].

Part C — Classes and Object-Oriented Programming (28 points) Consider the following code. class Tracer { std::string name;public: Tracer(std::string name) : name(name) { std::cout
