In file AAA.c
const char CMD_Fire[] = "FIRE";
In file BBB.c
extern const char CMD_Fire[];
It seems that, the compiler is not able to know the size of CMD_Fire[], when compiling BBB.c
So, I have to hard code the size of CMD_Fire[] in BBB.c
Then, if I change the command to "Fire it!", I will need to change the size of CMD_Fire[] everywhere.
Is there any skill to handle this?
