If you don’t declare a function and it only appears after being called, it is automatically assumed to be int
, so in your case, you didn’t declare
void my_print (char *); void my_print2 (char *);
before you call it in main, so the compiler assume there are functions which their prototypes are int my_print2 (char *);
and int my_print2 (char *);
and you can’t have two functions with the same prototype except of the return type, so you get the error of conflicting types
.
As Brian suggested, declare those two methods before main.
