IN C++
Design a class called Date that has integer data members to store month, day, and year. The class should have a three-parameter (day-of-month, month, year) default constructor that allows the date to be set at the time a new Date object is created. If the user creates a Date object without passing any arguments , or if any of the values passed are invalid, the default values of 1, 1, 2001 (i.e., January 1, 2001) should be used (see below for the definition of invalid values ). The class should have member functions to print the date in the following formats:
3/15/13 (printNumerical)
March 15, 2013 (printMonthFirst)
15 March 2013 (printDateFirst)
The following are invalid values :
For day of month: any value less than 1 or greater than 31 (so February 30 or April 31 would be acceptable)
For month: any value less than 1 or greater than 12
For year: any value less than 0
Then,
Write a program that uses the Date class just defined. The program prompts "date information: " and then reads three integers : the day of month. the month and the year. The program then prints the date three times, each time on a line by itself. The first time the date is in numerical format, the second in month-first format, and the third time in date first format.
Here is one sample run:
Explanation / Answer
#include <iostream>
using namespace std;
class Date {
private:
int day, month, year;
public:
Date() {
day = 1;
month = 1;
year = 2001;
}
Date(int d, int m, int y){
day = d;
month = m;
year = y;
}
void printNumerical() {
cout<<day<<"/"<<month<<"/"<<year<<endl;
}
void printMonthFirst() {
cout<<getMonth(month)<<" "<<day<<", "<<year<<endl;
}
void printDateFirst() {
cout<<day<<" "<<getMonth(month)<<" "<<year<<endl;
}
string getMonth(int month){
if(month == 1){
return "January";
}
else if(month == 2){
return "February";
}
else if(month == 3){
return "March";
}
else if(month == 4){
return "April";
}
else if(month == 5){
return "May";
}
else if(month == 6){
return "June";
}
else if(month == 7){
return "July";
}
else if(month == 8){
return "August";
}
else if(month == 9){
return "September";
}
else if(month == 10){
return "October";
}
else if(month == 11){
return "November";
}
else if(month == 12){
return "December";
}
}
};
int main()
{
int day, month, year;
while(day < 1 || day > 31) {
cout<<"Enter the day: ";
cin >> day;
}
while(month < 1 || month > 31) {
cout<<"Enter the month: ";
cin >> month;
}
cout<<"Enter the year: ";
cin >> year;
Date d1;
d1.printNumerical();
d1.printMonthFirst();
d1.printDateFirst();
Date d2(day, month, year);
d2.printNumerical();
d2.printMonthFirst();
d2.printDateFirst();
return 0;
}
Output:
sh-4.2$ g++ -std=c++11 -o main *.cpp
sh-4.2$ main
Enter the day: 15
Enter the month: 3
Enter the year: 2014
1/1/2001
January 1, 2001
1 January 2001
15/3/2014
March 15, 2014
15 March 2014
