Student Report Card with Logging

You are to design and implement a Student class, a Grade class, as well as a Logger class implemented as a Singleton in C++. Then you will write some client tests in main() to demonstrate the output.

Student Class

• You need to implement the big three: Destructor, Copy Constructor, and operator=.
• Your class needs to provide the following data members:
  • id, int, needs to be unique
  • name, string
  • grades, vector
• Your class needs to provide the following member functions:
  • int calculateFinal(), returns a value from 0-100
  • string calculateLetterGrade(), returns a string representation of a letter grade (A+, B-, etc).
  • string printReport(), returns a string report
  • Standard Accessors and Mutators, and any private helper functions
• Each class must use the same instance of your logger, in each method, to print to the command line what the return value of the method will be.

Grade Class

• This class needs to provide the following data members:
  • pointsEarned, int
  • totalPoints, int
  • weight, double
  • assignment, string

Logger Class

• You need to make this a proper singleton.
• Your class needs to provide the following member function:
  • void log(string output), prints the contents to cout.

main()

• You need to devise a set of tests in main() to exercise both the Student class and your Logger singleton. A minimum amount of rigor in testing the code inside of the Student Class should be present.
• The same logger should log inside of each Student class, as well as the tests.
