A(n) ________ is a type of file that organizes data in rows and columns.

Given the following definition for a map, which code fragment will correctly iterate through the map and output each item?

A. for (std::map::iterator itr = mymap.begin(); itr != mymap.end(); itr++) cout << itr << " " << *itr << endl; B. for (int i = 0; i < mymap.size; i++) cout << i << " " << mymap[i] << endl; C. for (auto item : mymap) cout << item.first << " " << item.second << endl;

Here is a list of file names with extensions. Pick at least one that could properly be the implementation file and at least one that can properly serve as interface file.

a) File.cxx b) File.hxx c) File.cc d) File.h e) File.cpp f) File.hpp
