Performance question
Author
Hello!
I am writing 3D application and i will need vectors. Now i have:
but i want do do classes like
Now if i declarate vector i for example write "float Pos=Vector.x" it will be faster for structure/class or maybe it will be exacly the same performance? Thank you for your answers.

Go with the class. They are the same speed, and the same size in memory (unless you have virtual functions).
Only use structs if you don''t need to have any functions/constructors/destructors.
(That last bit is just my opinion though.)
