代碼如下：

teacher.cpp的代碼：

#include<iostream>
#include<string>
#include"teacher.h"

using namespace std;

void teacher::setName(string name)
{m_strName=name;}
string teacher::getName()
{return m_strName;}

void teacher::setAge(int age)
{m_iAge=age;}
int teacher::getAge()
{return m_iAge;}

teacher::teacher(){
?? m_strName="jim";
?? m_iAge=114;
?? cout<<"teacher()"<<endl;
?
}
teacher::teacher(string name,int age);
int main(){

?teacher t;
?t.setName("kongzi");
?cout<<t.getName()<<endl;
?t.setAge(111);
?cout<<t.getAge()<<endl;

?system("pause");
?return 0;

}

這是·teacher.h的代碼：

#include<string>

using namespace std;
class teacher{

?? public:
??? teacher();
??? teacher(string name,int age);
??? void setName(string name);
??? string getName();
??? void setAge(int age);
??? int getAge();
?? private:
??? string(m_strName);
??? int(m_iAge);

};

這是demo.cpp的代碼：

#include<iostream>
#include<string>
#include"teacher.h"

using namespace std;

int main(void){
?teacher t1;
?teacher t2("merry", 12);
??? cout<<t1.getName()<<t1.getAge()<<endl;
?cout<<t2.getName()<<t2.getAge()<<endl;
}

按照這樣的代碼運行會報如下錯誤：1>d:\vs 2010\project\test8\test8\teacher.cpp(23): error C2761: “{ctor}”: 不允許成員函數(shù)重新聲明

?

就是不知道怎么解決，老師不也在teacher.cpp里面定義了兩個構(gòu)造函數(shù)嗎?有參和無參，怎么我這里定義會顯示是重新申明了？表示不懂
