Transfer (Trade) System is about adding players(when come to buying player) and also removing Player(when come to selling the players)
So am I right that I should learn C++ Data Structures and Algorithms for management games or it is just C++ Data Structures?
Kind of like asking if you should learn pedalling or staying upright when riding a bike. Data structures aren't useful without algorithms (I suspect the data structures course will give you algorithms to use with the data structures though).
A trade is just a compound operation anyway: acquire player X from team A and release player Y and give it to team A.
Thanks 
What book or website that I could learn in C++ Data Structures and Algorithms that you recommend
cheers
google would be the first website I would try.
If you are doing a sports management game with a lot of players you are probably going to want to use a database anyway, so learn some database stuff (e.g. SQL queries).
Learn about the standard library containers,
Specifically, look for a tutorial on "STL maps" to get started.
Then learn about the rest of stl.
SQL queries?
C++ STL?
Thanks guys, I will learn those(Yes, it does take time to learn them) and I hoping to make Premier League Football Manager(Just one League only for starter) then take it from there and see how goes
