Struct in file.c

Is it any easier to use a class in a c++ file?

essentially i'm just kinda playing at the moment so its not 100% essential, but i have a struct.c file with :

struct SPlayer{
	int PlayerScore;
	int PlayerID;
	int PlayerHealth;
	int X;
	int Y;
	int Z;
};

then in main.bmx i import the struct.c file wanted to be able to be able to something simple like:

Player1:SPlayer;
Player1.PlayerScore = 10;

but guessing its not so easy
