Question

Design a class Holiday that represents a holiday during the year. This class has three private data members:

• name: A string that represents the name of holiday.
• day: An integer that holds the day of the month of holiday.
• month: A string that holds the month the holiday is in.

1. Write a default constructor that initializes each data member of class such that name with NULL, day with 0 and month with NULL

Holiday()

2. Write a constructor that accepts the arguments for each data member such that string n assigned to name, int d to day and string m to month.

Holiday(string &n, int d, string &m)

Note*:Use member function initialization for all data members.

3. Generate getter setter of each member variable: such that name should never be greater than 50 characters, day should never be negative and month should not be greater than 10 characters.

• bool setName(string &s)
• string getName()
• bool setDay(int u)
• int getDay()
• bool setMonth(string &p)
• string getMonth()

4. Write a function inSameMonth (outside class) which takes two Holiday objects as arguments, compares two objects of the class Holiday, and returns true if they have the same month otherwise false.

bool inSameMonth (Holiday &a, Holiday &b)

5. Write a function avgDate (outside class) which takes an array of type Holiday and its size as its argument and returns a double value that is the average of the entire day data member in the Holiday array arr. You may assume that the array is full (i.e. does not have any NULL entries).

double avgDate(Holiday arr[], int size)

//Task 2

Holiday();
Holiday( string &n, int d, string &m);
bool setName( string &s);
string getName() ;
bool setDay(int u);
int getDay() ;
bool setMonth( string &p);
string getMonth() ;
bool inSameMonth ( Holiday &a, Holiday &b);//globle function
double avgDate(Holiday arr[], int size);//globle function

Use only the given function as it will be run in gtest.Write the code in c++.

Gtest:

TEST(Holiday, Constructors) {
Holiday a ("Day 1",1,"September");

ASSERT_EQ(0, a.getName().compare("Day 1"));
ASSERT_EQ(0, a.getMonth().compare("September"));
ASSERT_EQ(1, a.getDay());
}
TEST(Holiday, inSameMonth) {
Holiday a ("Day 1",1,"Sep");
Holiday b ("Day 2",2,"Feb");
Holiday c ("Day 1",1,"Sep");
  
  
ASSERT_EQ(0, inSameMonth(a,b));
ASSERT_EQ(1, inSameMonth(a,c));
  

}
TEST(Holiday, avgDate) {
Holiday a ("Day 1",1,"September");
Holiday b ("Day 2",2,"September");
//cout<<inSameMonth(a,b)<<endl;
Holiday * ptr=new Holiday [2];
*ptr=a;
*(ptr+1)=b;
  
  
ASSERT_EQ(1.5, avgDate(ptr, 2));
  

}

int main(int argc, char **argv) {
testing::InitGoogleTest(&argc, argv);
return RUN_ALL_TESTS();
}

It is mandatory to pass the gtest part.If not then create a main file and put the test data in there to confirm.

Write the code in c++.

REMARK:

It is not possible to pass constants to call by reference methods, hence in all functions using call by reference I have replaced "datatype &var" with "datatype const &var" to avoid errors.
