For a project in C++ we are supposed toDesign a class named Month. The class should have the following private members:-name: a string object that holds the name of the month, such as January.-monthName: an integer value that holds the number of the month. For example, January would be 1, February would be 2, and so on. Valid values for this variable should be from 1 to 12.In addition, provide the following member functions:-a default constructor that sets monthNumber to 1 and name to "January"-a constructor that accepts the name of the month as an argument and finds and prints how many days in that month. For example, January has 31 days, and so on.

using namespace std;

 Month (char firstLetter, char secondLetter, char thirdLetter);

   defaultMonth.outputMonth_num();

   defaultMonth.outputMonthLetters();

   //

   //

   cout << "Enter a month number: ";

   cin >> monthNum;

   Month testMonth1(monthNum);

   testMonth1.outputMonth_num();

   testMonth1.outputMonthLetters();

   //

   // Construct a month using the constructor with three letters as arguments

   //

   cout << "Testing the constructor with 3 letters as arguments ..." << endl;

   cout << "Enter the first three letters of a month (lowercase): ";

   cout << endl;

   Month testMonth2(firstLetter, secondLetter, thirdLetter);

   testMonth2.outputMonth_num();

   testMonth2.outputMonthLetters();

   //

   // See if user wants to try another month

   //
