I have multiple errors in multiple files, so bare with me$.$ In one of my class implementation files, I am getting an error that this section of code:

void Match::assignteamCoach$()$

$\{$

if $(!$teamCoach$)$

$\{$

teamCoach $=$ teamCoach;

$\}$

else

$\{$

std::cout $<<$ "A Coach has already been assigned." $<<$ std::endl;

$\}$

$\}$

has this error: no operator $"!"$ matches these operands

this snippet:

if $($m$.$teamCoach.empty$())$

$\{$

output $<<"$No coach has been assigned.";

$\}$

else

$\{$

output $<<$ "Team Coach: $"$;

output $<<$ m$.$teamCoach $<<$ std::endl;

$\}$

has this error: class Coach has no member "empty"

and in my main cpp file, this code snippet:

std::string teamName, matchLocation, matchOpponent;

int month, day, year;

char slash;

Date matchDate;

std::cout $<<$ "Team Name: $"$;

std::getline$($std::cin, teamName$)$;

std::cout $<<$ "Match Location: $"$;

std::getline$($std::cin, matchLocation$)$;

std::cout $<<$ "Match Opponent: $"$;

std::getline$($std::cin, matchOpponent$)$;

std::cout $<<$ "Match Date $($mm$/$dd$/$yyyy$)$: $"$;

std::cin $>>$ month $>>$ slash $>>$ day $>>$ slash $>>$ year;

matchDate.setDate$($month$,$ day, year$)$;

Match newMatch$($teamName$,$ matchLocation, matchOpponent, matchDate$)$;

gives this error on the last line: no instance of constructor "Match::Match" matches the Inheritence argument list

Any help would be appreciated.
