Necessary skills: In this assignment, you’ll create a C++ Date class that stores a calendar date.. You’ll test it using the supplied test main() function (attached below). In your class, use three private integer data member variables to represent the date (month, day, and year). Supply the following public member functions in your class. The class data members should be set to correct values by the methods so the get and print member functions simply return or print the data member values. The constructor methods must validate their parameter values (eg. verify the month parameter is within the range of 1 to 12) and only set the Date data members to represent a valid date, thus ensuring the Date object’s data members (i.e. its state) always represent a valid date. The print member function should output the date in the format MM/DD/YYYY with leading zeros as needed, using the C++ IOStreams cout object. To get formatting to work with C++ IOStreams (cout), look at the setw() and setfill() manipulator descriptions, or the width() and fill() functions in the chapter on the C++ I/O System. #include #include #include using namespace std; // or use individual directives, e.g. using std::string; class Date { // methods and data necessary }; Use separate files for the Date class definition (in Date.h), implementation of the member functions (Date.cpp), and the attached test main() function (DateDemo.cpp). The shortest member functions (like getDay() ) may be implemented in the class definition (so they will be inlined). Other member functions should be implemented in the Date.cpp file. Both Date.cpp and DateDemo.cpp will need to #include the Date.h file (since they both need the Date class definition in order to compile) and other include files that are needed (e.g. iostream, string, etc). // DateDemo.cpp // Note – you may need to change the definition of the main function to // be consistent with what your C++ compiler expects. int main() { Date d1; // default ctor Date d2(7, 4, 1976); // July 4’th 1976 Date d3(0, 15, 1880);// Adjusted by ctor to January 15’th 1900 d1.print(); // prints 01/01/2000 d1.printLong(); // prints 1 January 2000 cout << endl; d2.print(); // prints 07/04/1976 d2.printLong(); // prints 4 July 1976 cout << endl; d3.print(); // prints 01/15/1900 d3.printLong(); // prints 15 January 1900 cout << endl; cout << "object d2's day is " << d2.getDay() << endl; cout << "object d2's month is " << d2.getMonth() << " which is " << d2.getMonthName() << endl; cout << "object d2's year is " << d2.getYear() << endl; } Use the attached DateDemo.cpp source file to test your class. Save this source as a separate DateDemo.cpp source file that contains the supplied main() function. Compile your Data.cpp file first, then this DateDemo.cpp next. Here is the attached DateDemo.cpp code // DateDemo.cpp #include #include #include using std::cout; using std::endl; using std::setfill; using std::setw; using std::string; #include “Date.h” // note – you may need to change the definition of the main function to // be consistent with what your C++ compiler expects. //int _tmain(int argc, _TCHAR* argv[]) int main() { Date d1; // default ctor Date d2(7, 4, 1976); // July 4’th 1976 Date d3(0, 15, 1880);// Adjusted by ctor to January 15’th 1900 d1.print(); // prints 01/01/2000 d1.printLong(); // prints 1 January 2000 cout << endl; d2.print(); // prints 07/04/1976 d2.printLong(); // prints 4 July 1976 cout << endl; d3.print(); // prints 01/15/1900 d3.printLong(); // prints 15 January 1900 cout << endl; cout << "object d2's day is " << d2.getDay() << endl; cout << "object d2's month is " << d2.getMonth() << " which is " << d2.getMonthName() << endl; cout << "object d2's year is " << d2.getYear() << endl; return 0; }
