Question

n this programming assignment, you need to create 3 files.

1. DateType.h

2. DateType.cpp

3. A test driver for testing the class defined in the other 2 files. You can name your file in the way you like. Remember it must be a .cpp file.

In DateType.h file, type these lines:

// To declare a class for the Date ADT // This is the header file DateType.h

class DateType

{
public:

void Initialize(int newMonth, int newDay, int newYear); int GetYear() const;
int GetMonth() const;
int GetDay() const;

private:
int year;

int month;

int day; };

// Class implementation // DateType.cpp

#include "DateType.h"

void DateType::Initialize(int newMonth, int newDay, int newYear)

{
year = newYear;

month = newMonth;

day = newDay; }

int DateType::GetMonth() const

{
return month;

}

In DateType.cpp file, type these lines:

int DateType::GetDay() const

{
return day;

}

int DateType::GetYear() const

{

return year; }

In you test driver, type in these lines:

// test driver
// I give the file name: testDriver.cpp
// To compile, type c++ DataType.cpp testDriver.cpp, this will generate an a.out executable.
// Or, type c++ Type.cpp testDriver.cpp –o testdriver, this will generate an executable named testdriver.

#include "DateType.h" #include <iostream>

using namespace std;

int main()

{
DateType today;

DateType anotherDay; today.Initialize(9, 24, 2003); anotherDay.Initialize(9, 25, 2003);

cout << "Today is " << today.GetMonth() << "/" << today.GetDay() << "/" << today.GetYear() << endl;

cout << "Anotherday is " << anotherDay.GetMonth() << "/" << anotherDay.GetDay() << "/" << anotherDay.GetYear() << endl;

return 0; }

Once you have the 3 files ready, you can compile them. The compile command is in the comments of the test driver.

After the compilation, you run the program, and see what output you get.
Now, modify the code to initialize 2 different dates, compile and run it, and see what the output is.

Answer 1

In the given code, in testDriver.cpp file two different dates are given ('today' and 'anotherDay').

To compile and execute the code:
command1 : generate the object code of DataType.cpp (creates DataType.o)
g++ -c DateType.cpp

command2 : generate the object code of testDriver.cpp (creates testDriver.o)
g++ -c testDriver.cpp

command3 : make executable file 'testdriver' by linking DataType.o and testDriver.o
g++ DateType.o testDriver.o -o testdriver

command4 : execute 'testdriver'
./testdriver

Code screenshot and output:

DateType.h

DateType.cpp

testDriver.cpp

Output file

As asked in the question, if we modify the dates, the modified dates will be printed.

Code:

DateType.h

class DateType{
   public:
   void Initialize(int newMonth, int newDay, int newYear);
   int GetYear() const;
   int GetMonth() const;
   int GetDay() const;

   private:
   int year;
   int month;
   int day;
};

DateType.cpp

#include "DateType.h"

void DateType::Initialize(int newMonth, int newDay, int newYear){
   year = newYear;
   month = newMonth;
   day = newDay;
}

int DateType::GetMonth() const{
   return month;
}

int DateType::GetDay() const{
   return day;
}

int DateType::GetYear() const{
   return year;
}

testDriver.cpp

#include "DateType.h"
#include <iostream>
using namespace std;

int main(){
   DateType today;
   DateType anotherDay;
   today.Initialize(9, 24, 2003);
   anotherDay.Initialize(9, 25, 2003);
   cout<<"Today is " <<today.GetMonth()<<"/"<<today.GetDay()<<"/"<<today.GetYear()<< endl;
   cout<<"Anotherday is "<<anotherDay.GetMonth()<<"/"<<anotherDay.GetDay()<<"/"<<anotherDay.GetYear()<<endl;
   return 0;
}
