Question

(Problem is from the textbook Data Structures using C++)

Add a function to the dateType class.

The function's name is compareDates.

Its prototype is

int compareDates(const dateType& otherDate;

The function returns -1 if otherDate is greater than than this date

The function returns 0 if otherDate equals this date

The function returns 1 if otherDate is less than this date

Examples

dateType d1(1, 1, 2019);

dateType d2(11,1, 2019)

d1.compareDates(d2) returns -1

d2.compareDates(d1) returns 1

d2.compareDates(d2) returns 0

hi i have answered your question hope this will be helpful to you as i need to run the program and verify hence i have make a seprate class and function there so you too can verify the function if it working as expected ,hope you will understand , kindly give a thumbs up , and if need any clarification you can comment i will reply accordingly.

code:-

#include<iostream>
using namespace std;

class dateType
{
int day;
int month;
int year;
public:
int compareDates(const dateType& otherDate); //Function Prototype to compare date
dateType(int d,int m,int y) { // constructor to set the values of the variable so we ever a object will be creat this will set the value
this->day= d;
this->month= m;
this->year=y;
}
  
};
int dateType :: compareDates(const dateType& obj) { // Function to compare the dates comapring each day month and year
if(this->day== obj.day && this->month == obj.month && this->year == obj.year)
return 0;
else if(this->year <= obj.year && this->month <= obj.month && this->day < obj.day)
return -1;
else
return 1;
}
int main()
{
dateType d1(1,1,2019),d2(11,1,2019); //Creating objectes of the datetypes class
int res = d1.compareDates(d2);
cout<<"res is "<<res<<endl;
res = d2.compareDates(d1);
cout<<"res is "<<res<<endl;
res = d2.compareDates(d2);
cout<<"res is "<<res<<endl;
return 0;
}

output:-
