代码如下：如有帮助，请采纳一下，谢谢。

#include <iostream>
using namespace std;

class Student
{
private:
	int mId;
	int mScoreMath;
	int mScoreEng;
	int mScoreC;
public:
	Student(){}
	Student(int id){mId = id;}
	Student(int id,int m,int e,int c){mId = id;mScoreMath=m;mScoreEng=e;mScoreC=c;}
	void setScore(int m,int e,int c){mScoreMath = m;mScoreEng = e;mScoreC = c;}
	float average()	{return (mScoreC + mScoreEng + mScoreMath)/3.0;}
	int sum(){return mScoreC + mScoreEng + mScoreMath;}
	void print(){cout << "学号:" << mId << "  数学:" << mScoreMath<< "  英语:" << mScoreEng << "  C语言:" << mScoreC <<endl;}
};

int main()
{
	Student st(1001);
	st.setScore(88,98,89);
	cout << "平均分:" << st.average() << endl;
	cout << "总分:" << st.sum() << endl;
	st.print();
	return 0;
