One day Bob got a task to process a text file line by line. He decides to use C++, as he knows that not many languages out there can compete with its speed. As C++ is still an uncouth beast for Bob, he decides to ask Google ChatGPT about the most popular approach to read a file line by line in C++, to have some initial code for start and avoid fluttering through the endless pages of C++ Standard Library documentation.

Bob is a junior developer with big ambitions. He is serious about his craft and reputation, so he really wants to make sure that his code is tasty – fast, elegant, and the best of its kind.

When Bob asked Google ChatGPT for the most popular approach to read a file line by line in C++, the solution was based on std::getline() function from the Standard Library.

Bob knows that ChatGPT solution is slow, because every line in this solution is returned by copy. Bob is going to fix this and find more optimal approach.
