为什么运行时出现one or more multiply defined symbols found

[zhouchenbb]

我在书上拷贝的程序运行时出现这样的问题，不知道是不会死我的VC6。0有问题
程序：、
#include <iostream.h>
#include <string.h>

#define N 20

class Employee
{
private:
//* * 1 * *
char name[N];char street[N];char city[N];char zip[N];
public:
Employee(char *n, char *str, char *ct, char *z);
void change_name(char *n);
void display();
bool equal(char *n);
};

Employee::Employee(char *n,char *str,char *ct, char *z)
{
//* * 2 * *
strcpy(name, n);strcpy(street, str);strcpy(city, ct); strcpy(zip, z);
}

void Employee::change_name(char *n)
{
//* * 3 * *
strcpy(name, n);
}

bool Employee::equal(char *n)
{
//** 4 **
return strcmp(name, n)==0;
}

void Employee::display ()
{
cout << name << " " << street << " ";
cout << city << " "<< zip << endl;
}

void main(void)
{
Employee emp[5] =
{
Employee("张建","武侯路311号", "成都", "600000"),
Employee("李明","青牛街201号", "宜宾", "500000"),
Employee("赵刚","南山路112号", "重庆", "400000"),
Employee("李欣","南京路244号", "上海", "200000"),
Employee("周彪","车城路115号", "沈阳", "100000")
};
for(int i=0;i<5;i++)
emp[i].display();
cout<<"\n修改\"周彪\"的名字为\"黎明\"\n"<<endl;
//** 5 **
for (int j=0;j<5;j++)
{
if (emp[j].equal("周彪")) {
emp[j].change_name("黎明");
emp[j].display();
break;
}
}
}

刚才试了一下，vc6顺利通过，抹油问题。

[sdoaiya]

虽然不大明白 但还是支持一下

[dingshaofengbinbin]

有问题吗？？？？

[冻结]

#include <iostream>

#include <string>
using namespace std;


#define N 20

class Employee
{
private:
	//* * 1 * *
	char name[N];char street[N];char city[N];char zip[N];
public:
	Employee(char *n, char *str, char *ct, char *z);
	void change_name(char *n);
	void display();
	bool equal(char *n);
};

Employee::Employee(char *n,char *str,char *ct, char *z)
{
	//* * 2 * *
	strcpy(name, n);strcpy(street, str);strcpy(city, ct); strcpy(zip, z);
}

void Employee::change_name(char *n)
{
	//* * 3 * *
	strcpy(name, n);
}

bool Employee::equal(char *n)
{
	//** 4 **
	return strcmp(name, n)==0;
}

void Employee::display ()
{
	cout << name << " " << street << " ";
	cout << city << " "<< zip << endl;
}

void main(void)
{
	Employee emp[5] =  
	{
		Employee("张建","武侯路311号", "成都", "600000"),
		Employee("李明","青牛街201号", "宜宾", "500000"),
		Employee("赵刚","南山路112号", "重庆", "400000"),
		Employee("李欣","南京路244号", "上海", "200000"),
		Employee("周彪","车城路115号", "沈阳", "100000")
	};
	for(int i=0;i<5;i++)
		emp[i].display();
	cout<<"\n修改\"周彪\"的名字为\"黎明\"\n"<<endl;	
	//** 5 **
	for (int j=0;j<5;j++)
	{
		if (emp[j].equal("周彪")) {
			emp[j].change_name("黎明");
			emp[j].display();
			break;
		}
	}
}

VS2005没问题。

#include <iostream.h>
#include <string.h>
这个VC6应该支持呀。

[dxms8]

vs2008也表示木油问题。。

[dxms8]

vc6表示木油问题...

[qazwsx123asdfadf]

VS2008表示不支持

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

fatal error C1083: 无法打开包括文件:“iostream.h”: No such file or directory


最好用

#include <iostream>
#include <string>
using namespace std;

[smingr]

还是用c++
#include<iostream>
#include<string>

using namespace std;
我先前也出过类似问题

[arong1234]

你应该贴出完整错误信息,这样会有帮助

[skinnymonkey]

VC 下面除了有个error list tab, 应该还有output tab, 把信息考上来。

[doublearmy1]

可能是你的后缀错了吧，你是.c

[doublearmy1]

你没有建别外一个工程吧，好像是有两个main，因为信息太少了，只能猜了

[tomatobin]

我用vc 6没有问题
