Below is saved as a diceroll. H header file
Extern int roll_count;
Int roll_n_dice (int dice, int sides);
Created called diceroll. C source file
In the source file defines the roll_n function,
Then in the main function in the source file contains a header file
#include

#include
# include "diceroll. H"
Compile error, display an undefined roll_n function,
If add # include "diceroll. C", that it is no meaning to this header file does not,

CodePudding user response:

And see if it is in diceroll. C file forgot to include inside diceroll. H, if not, see if the function name wrong,
Compile error, display an undefined roll_n function, roll_n function and the roll_n_dice above is the same here? Is it your shorthand, or an error that quote?

CodePudding user response:

Check the extern here? The defined in other places if no may cause problems
