Write a Program in C++ That Define Class GradeBook With a Member Function That Takes a Parameter and Create a GradeBook Object and Call its DisplayMessage Function

// Define class GradeBook with a member function that takes a parameter,

// create a GradeBook object and call its displayMessage function.

#include <iostream>

#include <string> // program uses C++ standard string class

using namespace std;

// GradeBook class definition

class GradeBook

{

public:

   // function that displays a welcome message to the GradeBook user 

   void displayMessage( string courseName ) const

   {

      cout << "Welcome to the grade book for\n" << courseName << "!" 

         << endl;

   } // end function displayMessage

}; // end class GradeBook  

// function main begins program execution

int main()

{

   string nameOfCourse; // string of characters to store the course name

   GradeBook myGradeBook; // create a GradeBook object named myGradeBook

   

   // prompt for and input course name

   cout << "Please enter the course name:" << endl;

   getline( cin, nameOfCourse ); // read a course name with blanks

   cout << endl; // output a blank line

   // call myGradeBook's displayMessage function

   // and pass nameOfCourse as an argument

   myGradeBook.displayMessage( nameOfCourse );

} // end main
