I know ya'll have probably seen this one a thousand times but would appreciate some help. Here's the code:
Header File:
Main File:Code:/* The game of paper, rock, scissors. */ #include <ctype.h> /* for isspace() */ #include <stdio.h> /* for printf(), etc */ #include <stdlib.h> /* for rand() and srand() */ #include <time.h> /* for time() */ enum p_r_s1 {paper, rock, scissors, game, help, instructions, quit}; enum outcome {win, lose, tie, error}; typedef enum p_r_s1 p_r_s1; typedef enum outcome outcome; outcome compare(p_r_s1 player_choice, p_r_s1 machine_choice); void prn_final_status(int win_cnt, int lose_cnt); void prn_game_status(int win_cnt, int lose_cnt, int tie_cnt); void prn_help(void); void prn_instructions(void); void report(outcome result, int *win_cnt_ptr, int *lose_cnt_ptr, int *tie_cnt_ptr); void report(outcome result, char *player_choice, char *machine_choice); p_r_s1 selection_by_machine(void); p_r_s1 selection_by_player(void);

I keep getting the following errors:Code:#include "p_r_s1.h" p_r_s1 selection_by_machine(void) { return ((p_r_s1) (rand() % 3)); } p_r_s1 selection_by_player(void) { char c; p_r_s1 player_choice; printf("Input p, r, or s: "); scanf(" %c", &c); switch (c) { case 'p': player_choice = paper; break; case 'r': player_choice = rock; break; case 's': player_choice = scissors; break; case 'g': player_choice = game; break; case 'i': player_choice = instructions; break; case 'q': player_choice = quit; break; default: player_choice = help; break; } return player_choice; }

I'm told that the function prototype and definition don't match number of items and correct types in the header and main files but I can't see where, my eyes hurt looking for it
Thanks
