Getting two errors and warning when compiling this code any help would be great.

Code:
#include <stdio.h>
#define SONG  "Say It Aint So"
#define SHOW  "Survivorman"
int menu (void);
void song (void);
void show (void);
int QUIT(void);
int main(void)

                     break;
         case SONG:  song();
                     break;
         default:    printf("Oops!  An invalid choice slipped through.  ");
                     printf("Please try again.\n");
