Find the error in the code. Don't change the code in main, manipulate the class the work with the main. What needs to be changed so the code can compile?

#include using namespace std; class Date { public: Date(int mn, int dy, int yr) : month(mn) {}; int getMonth(); void setMonth(int mn); private: int month;

}; int Date::getMonth() { return month; }

void Date::setMonth(int mn) { month = mn; }

int main() { const Date BirthDate(1, 18, 1953); BirthDate.getMonth(); return 0;

}
