Segmentation fault is a memory error. Or going beyond the bounds of the array, or something is wrong with the pointers.
I suspect that you don't have 50 lines in the file (I'm too lazy to count). So you get out of the array boundary.
Well, or there are some extra line breaks, there are spaces. so fin.eof() is not executed after the last line is read. Then you try to read something else, but you get back an empty string. This would not be a problem, but then you try to cram it all into the 51st element of the array.
I advise you to use std::vector instead of define N and a static array. In the file read loop, push_back the new object into the vector (better yet, emplace_back to save unnecessary copying).
When outputting, take the size() of your vector.
If you notice an extra book at the end with empty data in the output, then you can add an input check - if at least one of the 5 lines is empty, then you do not need to create a new book.
