我是 C++ 的新手，我不明白我在这段代码中哪里错了。我接受这个错误:
ClCompile:
1> Student.cpp
1>Student.obj : error LNK2019: unresolved external symbol "public: void __thiscall Student::setExamGrade(int,int)" (?setExamGrade@Student@@QAEXHH@Z) referenced in function _main
1>c:\users\administrator\documents\visual studio 2010\Projects\LAB1\Debug\LAB1.exe : fatal error LNK1120: 1 unresolved externals

1>Build FAILED.
你能帮帮我吗？代码在这里:
学生.h
#ifndef STUDENT_H
#define STUDENT_H
#include <string>
using namespace std;
class Student
{
private:
int ID;
string name;
int *exams;
public:
Student();
Student(int ID, string name);
void setExamGrade(int index, int grade);
int getOverallGrade();
void display();
};
#endif
学生.cpp
#include "Student.h"
#include <iostream>
using namespace std;
int total;
int count;
int average;
int exams[3];
void main() {
Student *s = new Student(123, "John");
s->setExamGrade(0, 80);
s->setExamGrade(1, 60);
s->setExamGrade(2, 95);
s->display();
delete s;
}
Student :: Student()
{
ID = 0;
name = "";
}
Student :: Student(int num, string text)
{
this->ID = num;
this->name = text;
}
void setExamGrade(int index, int grade)
{
exams[index] = grade;
total += exams[index];
count = index +1;
}
int getOverallGrade()
{
average = total/count;
return average;
}
void Student :: display()
{
cout << "ID:" << ID << "NAME:" << name << "GRADE:" << endl;
}
