UC知道C++新手问题，关于类的静态成员

出现连接错误。。。为什么呢？
源代码
#include <iostream>
using namespace std;
class cost
{
public:
int money;
char reason[20];
static int count;
public:
cost(char*reason,int money)
{
strcpy(this->reason,reason);
money=money;
count+=money;
}
static int show()
{
return count;
}
};
int cost::count=0;
void mian()
{
cost c1[2]={cost("买日用品",50),cost("伙食",70)};
cout<<"本周消费：";
cout<<cost::show();
}
源代码
#include <iostream>
using namespace std;
class cost
{
public:
int money;
char reason[20];
static int count;
public:
cost(char*reason,int money)
{
strcpy(this->reason,reason);
money=money;
count+=money;
}
static int show()
{
return count;
}
};
int cost::count=0;
void mian()
{
cost c1[2]={cost("买日用品",50),cost("伙食",70)};
cout<<"本周消费：";
cout<<cost::show();
}
main函数拼错了.. 你写成了mian
#include <iostream>
using namespace std;
class cost
{
public:
int money;
char reason[20];
static int count;
public:
cost(char*reason,int money)
{
strcpy(this->reason,reason);
money=money;
count+=money;
}
static int show()
{
return count;
}
};
int cost::count=0;
void main()
{
cost c1[2]={cost("买日用品",50),cost("伙食",70)};
cout<<"本周消费：";
cout<<cost::show();
}
