Remove line 24 from player.h

What are you doing is creating another vector with the same name as member, shadowing it. All changes are made to the local vector and do not persist.

This actually should give a warning. If you do not have warnings enabled in your IDE, do it. They help greatly. If they are enabled, read them.

Later you will probably want to separate saving another player in database and printing content of database, so you won't have to add another player if you just want to print all players in database.


@Dput You do see, that he had multiple problem with print function, right? Multiple responsibility, taking unnesesary parameters, doing unneeded work. Why not to show how it should be done instead of dirty patching existing code full of bad habits? Especially if it takes almost no work? (I did sugest to replace gotos but did not insist on it because it will truly lead to complete rewrite)

do you mean line 24 from database.h

[MiiNiPaa]

Yes, sorry. database.h
