I took these codes from Deitel's book directly, I tried them at both Linux gcc and Codeblocks on Windows and they both gave errors. Can you tell me why I am getting these errors? Am I doing a mistake by compiling them? Here is the code:
new.cpp:
#include <iostream>
using std::cout;
using std::endl;
#include "GradeBook.h" // include definition of class GradeBook
// function main begins program execution
int main()
{
// create two GradeBook objects
GradeBook gradeBook1( "CS101 Introduction to C++ Programming" );
GradeBook gradeBook2( "CS102 Data Structures in C++" );
// display initial value of courseName for each GradeBook
cout << "gradeBook1 created for course: " << gradeBook1.getCourseName()
<< "\ngradeBook2 created for course: " << gradeBook2.getCourseName()
<< endl;
return 0; // indicate successful termination
} // end mainGradeBook.h :
#include <string> // class GradeBook uses C++ standard string class
using std::string;
// GradeBook class definition
class GradeBook
{
public:
GradeBook( string ); // constructor that initializes courseName
void setCourseName( string ); // function that sets the course name
string getCourseName(); // function that gets the course name
void displayMessage(); // function that displays a welcome message
private:
string courseName; // course name for this GradeBook
}; //GradeBook.cpp:
#include <iostream>
using std::cout;
using std::endl;
#include "GradeBook.h" // include definition of class GradeBook
// constructor initializes courseName with string supplied as argument
GradeBook::GradeBook( string name )
{
setCourseName( name ); // call set function to initialize courseName
} // end GradeBook constructor
// function to set the course name
void GradeBook::setCourseName( string name )
{
courseName = name; // store the course name in the object
} // end function setCourseName
// function to get the course name
string GradeBook::getCourseName()
{
return courseName; // return object's courseName
} // end function getCourseName
// display a welcome message to the GradeBook user
void GradeBook::displayMessage()
{
// call getCourseName to get the courseName
cout << "Welcome to the grade book for\n" << getCourseName()
<< "!" << endl;
} // end function displayMessage
