I have three files, one is an interface, main file and the header file. I am using visual studio 2012 express. Below is the code:

// Exercise 3.11 Solution: ex03_11.cpp // Test program for modified GradeBook class. #include

include "GradeBook.h"

using namespace std;

// function main begins program execution int main() { // create a GradeBook object; pass a course name and instructor name GradeBook gradeBook( "CS101 Introduction to C++ Programming", "Professor Smith" );

// display initial value of instructorName of GradeBook object cout << "gradeBook instructor name is: " << gradeBook.getInstructorName() << "\n\n";

// modify the instructorName using set function gradeBook.setInstructorName( "Assistant Professor Bates" );

// display new value of instructorName cout << "new gradeBook instructor name is: " << gradeBook.getInstructorName() << "\n\n";

// display welcome message and instructor's name gradeBook.displayMessage(); } // end main

// Exercise 3.11 Solution: GradeBook.cpp // Member-function definitions for class GradeBook. #include

include "GradeBook.h"

using namespace std;

// constructor initializes courseName and instructorName // with strings supplied as arguments GradeBook::GradeBook( string course, string instructor ) { setCourseName( course ); // initializes courseName setInstructorName( instructor ); // initialiZes instructorName } // end GradeBook constructor

// function to set the course name void GradeBook::setCourseName( string name ) { courseName = name; // store the course name } // end function setCourseName

// function to retrieve the course name string GradeBook::getCourseName() { return courseName; } // end function getCourseName

// function to set the instructor name void GradeBook::setInstructorName( string name ) { instructorName = name; // store the instructor name } // end function setInstructorName

// function to retrieve the instructor name string GradeBook::getInstructorName() { return instructorName; } // end function getInstructorName

// display a welcome message and the instructor's name void GradeBook::displayMessage() { // display a welcome message containing the course name cout << "Welcome to the grade book for\n" << getCourseName() << "!" << endl;

// display the instructor's name cout << "This course is presented by: " << getInstructorName() << endl; } // end function displayMessage

    Code should be posted in code tags for readability purposes. As it stands now, I find it very difficult to separate things out in your post and feel less inclined to look closely as a result. Could you edit your post to include the proper formatting?
