Question

Programming language is C++. Show finished code and an example of the output on PuTTY when done. Use g++ -std=c++17 to compile the code with the chrono.cpp and chrono.h file on PuTTY.

3. (20 points) Start with Chrono,h and Chrono.cpp in section 9.8; for now put a dummy "return Sunday; or "return d in the last 3 functions on pages 337-338. Add a prefix operator to the Date class by putting the declaration in the Date class in Chrono,h and the definition in Chrono.cpp. The prefix operator should change a date to "tomorrow" using the following pseudocode: Date& operator ++0{ /addlto d //tomorrow, unless we were at the end ofthe month //if is date is false //need to change to first of next month set d to 1 if m is December Ineed to change to next year too set m to January increment y else increment m return this

Answer

main.cpp

#include <iostream>
#include "Chrono.h"
using namespace std;
int main()
{
Date T1;
cout<<"\n---T1---";
T1.displayTime();
++T1;
cout<<"\n---T1---";
T1.displayTime();
  
Date T2(28,2,2000);
cout<<"\n---T2---";
T2.displayTime();
++T2;
cout<<"\n---T2---";
T2.displayTime();
cout<<endl;
return 0;
}

Chrono.h

class Date
{
private:
int day; // 1 to 31
int month; // 1 to 12
int year;   
public:
Date();
Date(int d, int m,int y);
void displayTime(); // method to display time
Date& operator++(); // overloaded prefix ++ operator
};

Chrono.cpp

#include <iostream>
#include "Chrono.h"
using namespace std;
Date::Date()
{
day=1; //default date
month=1;
year=1900;
}
Date::Date(int d, int m,int y)
{
day=d;
month=m;
year=y;
}
// method to display time
void Date::displayTime()
{
cout<<"\nDate : "<<day<<"-"<<month<<"-"<<year;
}
// overloaded prefix ++ operator
Date& Date::operator++()
{
day++; // increment this object
if(month==1||month==3||month==5||month==7||month==8||month==10||month==12)
{
if(day > 31)
{
day=1;
month++;
if(month > 12)
{
month=1;
year++;
}
}
}
else if(month==2)
{
if(day > 28)
{
day=1;
month++;
if(month > 12)
{
month=1;
year++;
}
}
}
else
{
if(day > 30)
{
day=1;
month++;
if(month > 12)
{
month=1;
year++;
}
}
}
return *this;
}
