simple C++ help required

[power09]

Hello I am new to c++ and i cannot get rid of three errors in this project, they are highlighted in red text. I am obviously calling the functions incorrectly.

the compiler says for the first error : request for member 'precedes' in 'date', which is of none-class type 'Date*'

second error: request for member 'precedes' in 'trial', which is of none-class type 'Date*'

third error: request for member 'advance' in 'trial', which is of none-class type 'Date*'

I just dont understand what it wants me to do, This is probably very simple but as i said above C++ is new to me

I have included the the Date.h and Date.cpp files that the program uses because for all i know the problem lies there


Main.cpp
#include <cstdlib>
#include <iostream>
#include "Date.h"

using namespace std;

string Weekdays(Date* Date);
int main() {
string Event;
cout << "What date (d m y)? ";

int day,month,year;
while(cin >> day >> month >> year && getline(cin, Event)){
if(Event.length() > 0){
Event.erase(0,1);
}
if(Event.length() == 0){
Event = "this date was";
}

Date* event = new Date (day, month, year);
cout << Event;
cout << "on";
cout << Weekdays(event);
}

}

string Weekdays (Date* date) {

const string days[] = {"Sunday", "Monday", "Tuesday", "Wednesday",

"Thursday", "Friday", "Saturday"};


Date* trial = new Date(01, 01, 0001);
int weekday = 6;

if (date.precedes(trial)) {

return "Mysteryday";

} else {
while (trial.precedes(date)) {

trial.advance();

weekday = (weekday + 1) % 7;
}

return days[weekday];
}
}
Date.h
#ifndef DATE_H
#define DATE_H

public:

Date (int d, int m, int y);
int getDay ();

void setMonth (int month);
int getYear ();
void setYear (int year);
bool isLeapYear ();
int daysInMonth ();
void advance ();
bool precedes(Date* date);
};
#endif /* DATE_H */

date and trial are both pointers to an object of type 'Date'. To access the members of an object via a pointer, you must use the -> operator.

eg. date->precedes() or trial->advance()

If you are referencing an object directly (not via a pointer) you use the '.' operator. In your example this is done a number of times on the Event object which is of type string.

eg. Event.length() and Event.erase()
