Explanation / Answer
Given error list warning doesn't explicitly affect your program. If you want to remove the warning than you use to change the datatypes of the given comparision in the warning but it doesn't affect the running program so warning are fine.As for last two error change the folowing the error will be removed
273:57: error: no match for call to '(In_And_Out) (const char [35])'
line 273:-
in_and_out( " HUNT THE wump --------------- " );
Change to :-
in_and_out.message( " HUNT THE wump --------------- " );
286:59: error: invalid types 'const unsigned int[const unsigned int]' for array subscript
line 286:-
Set_PLAYER( saved[S_player] );
Change to:-
saved[S_player] = rand() % max_Rooms;
Set_PLAYER( saved[S_player] );
