Create a C class called myDate It should have the following

Create a C++ class called myDate.

It should have the following operations:

myDate() – default constructor. This will set the date to May 11, 1959 (A very important
date!!!)

myDate(int M, int D, int Y) – overloaded constructor. This will set the date to the values
passed in through the parameter list represented by Month, Day and Year.

void display() – display the date in the following format (May 11, 1959) Do NOT print a
linefeed after the date.

void incrDate(int N) – increment the date by N days.

void decrDate(int N) – decrement the date by N days.

int daysBetween(myDate D) – return the number of days between this date and the date D. If date D is a future date, the return value will be a positive int. If date D is in the past, the return value will be a negative int.

int getMonth() – return the month in integer form

int getDay() – return the day of the month

int getYear() – return the year

int getYearOffset() – return the number of days since the current year began.

Write a driver program that tests each operation

Solution

#include <iostream>

using namespace std;

class MyDate{
int day;
int month;
int year;
  
string getMonthString()
{
string monthStr = \"\";
switch(month)
{
case 1:
monthStr = \"January\";
break;
case 2:
monthStr = \"February\";
break;
case 3:
monthStr = \"March\";
break;
case 4:
monthStr = \"April\";
break;
case 5:
monthStr = \"May\";
break;
case 6:
monthStr = \"June\";
break;
case 7:
monthStr = \"July\";
break;
case 8:
monthStr = \"August\";
break;
case 9:
monthStr = \"September\";
break;
case 10:
monthStr = \"October\";
break;
case 11:
monthStr = \"November\";
break;
case 12:
monthStr = \"December\";
break;
}
return monthStr;
}
