错误一大堆，这个代码我已经看到过若干遍了。。。。
注意我加的说明

#include<iostream>
#include<string>
using namespace std;

class GradeBook
{
public:
GradeBook(){}////////////////////////////////////////////加了这个
GradeBook(string);
void setCourseName(string);
string getCourseName();
void displayMessage();
private:
string courseName;
};

//GradeBook.cpp
#include<iostream>
#include<string>
using namespace std;
//#include"GradeBook.h"

GradeBook::GradeBook(string name) ;//////////////////////少了分好
//setCourseName(name); //这个必须在函数里面才能这样用
void GradeBook::setCourseName(string name)
{/////这里是大括号，不是小括号
if (name.length()<=25)
courseName=name;
else
{courseName=name.substr(0,25);
cout<<"the Coursename that you entered is too long to express"
"so shorten it to: "
