加一句
#include<string>
string是标准库里的，你得包含进来
还有一处错误
void setCourseName(string name) 的定义里最后一条语句
cout<<"name \""<<name<<\"dxceeds maximun length(25).\n"<<"limiting courseName to frist 25 characters.\n"<<endl;
改成（<<后面多了一个反斜杠）
cout<<"name \n"<<name<<"dxceeds maximun length(25).\n"<<"limiting courseName to frist 25 characters.\n"<<endl;
