代码:
#include<iostream>
using namespace std;
template<class T>
int total(T &t)
{
return t.blance;
}
class CBank
{
public:
CBank(int b=0)
{
blance=b;
}
friend int total(CBank &t);
private:
int blance;
};
class BBank
{
public:
BBank(int b=0)
{
blance=b;
}
friend int total(BBank &t);
private:
int blance;
};
class GBank
{
public:
GBank(int b=0)
{
blance=b;
}
friend int total(GBank &t);
private:
int blance;
};
int main()
{
int tol=0;
CBank a1(20);
BBank a2(40);
GBank a3(50);
tol=total(a1)+total(a2)+total(a3);
cout<<"The total is "<<tol<<endl;
return 0;
}
一个有问题的小程序,请大家指教了!(把有元函数声明里的T改为具体的类也没能通过。) using namespace std;
template<class T>
int total(T &t)
{
return t.blance;
}
class CBank
{
public:
CBank(int b=0)
{
blance=b;
}
friend int total(CBank &t);
private:
int blance;
};
class BBank
{
public:
BBank(int b=0)
{
blance=b;
}
friend int total(BBank &t);
private:
int blance;
};
class GBank
{
public:
GBank(int b=0)
{
blance=b;
}
friend int total(GBank &t);
private:
int blance;
};
int main()
{
int tol=0;
CBank a1(20);
BBank a2(40);
GBank a3(50);
tol=total(a1)+total(a2)+total(a3);
cout<<"The total is "<<tol<<endl;
return 0;
}
