I am trying to write a program that will test for the birthday paradox. I need to run a series of experiments on randomly generated birthdays, which test this paradox for n = 5, 10, 15, 20,...,100 (n = number of people in any given room). I need to run at least 10 experiments for each value of n and it should output, for each n, the number of experiments for that n, such that two people in that test have the same birthday, But after running some lines of codes i am having problems on pointers...I need help here are the whole program

```
//birthday.cpp
#include "birthday.h"
Birthday::Birthday()
{
assignRandBirthday();
}
int Birthday::getMonth() {
return month;
}
int Birthday::getDay() {
return day;
}
int daysInMonth(int month) {
switch(month) {
case 1:
return 31;
case 2:
return 28;
case 3:
return 31;
case 4:
return 30;
case 5:
return 31;
case 6:
return 30;
case 7:
return 31;
case 8:
return 31;
case 9:
return 30;
case 10:
return 31;
case 11:
return 30;
case 12:
return 31;
}
}
void Birthday::assignRandBirthday()
{
month = (rand()%12)+1;
day = (rand()%daysInMonth(month))+1;
}
bool operator==(const Birthday &x, const Birthday &y)
{
if ((x->getMonth() == y->getMonth()) && (x->getDay() == y->getDay()))//i am getting errors here
return true;
else
return false;
}
