问题及代码：

main.cpp:

#include<iostream>#include"header.h"//using namespace std;int main(){    Stu s1,s2;    s1.setStudent("Lin daiyu", 98, 96); //对象置初值    s2.setStudent("Jia baoyu", 90, 88); //对象置初值    s1.show();//打印信息    s2.show();//打印信息    s1.setName("xue baochai");//重新置p1对象的名字    s1.show();    cout<<"s1.Name: "<<s1.getName()<<endl;//打印对象的名字    cout<<"s1.average: "<<s1.average()<<endl;//打印对象的成绩    return 0;}

student.cpp:

#include"header.h"#include<iostream>#include <string>double   Stu::average(){    return (chinese+math)/2;}float Stu::sum(){    return (chinese+math);}void Stu::setStudent(string x,float y,float z){    name=x;    chinese=y;    math=z;}void Stu::show(){    cout<<"Name:"<<name<<endl;    cout<<"Score:"<<chinese<<"    "<<math<<endl;    cout<<"average:"<<average()<<"     "<<"Sum:"<<sum();    cout<<endl;}void Stu::setName(string x){    name=x;}string Stu::getName(){    return name;}

header.h:

#include"header.h"#include<iostream>#include <string>double   Stu::average(){    return (chinese+math)/2;}float Stu::sum(){    return (chinese+math);}void Stu::setStudent(string x,float y,float z){    name=x;    chinese=y;    math=z;}void Stu::show(){    cout<<"Name:"<<name<<endl;    cout<<"Score:"<<chinese<<"    "<<math<<endl;    cout<<"average:"<<average()<<"     "<<"Sum:"<<sum();    cout<<endl;}void Stu::setName(string x){    name=x;}string Stu::getName(){    return name;}

运行结果：

知识点总结：

分文件后报错是在main函数但是同时也要考虑在别的文件中是不是有错，不能只盯着main函数，定义类函数的时候注意前缀和：：，做程序养成不断调整规范的习惯，能够方便查错，不要粗心！
