C++: Using ifstream with getline();

Question

Check this program

ifstream filein(\"Hey.txt\");
filein.getline(line,99);
cout<

        

Answer 1

The idiomatic way to read lines from a stream is thus:

{
    std::ifstream filein("Hey.txt");

    for (std::string line; std::getline(filein, line); )
    {
        std::cout << line << std::endl;
    }
}

Note:

• No close(). C++ takes care of resource management for you when used idiomatically.

• Use the free std::getline, not the stream member function.
