简单写个示例：【VS2012编译运行通过】
头文件，定义一个类模板（含有虚函数）和需要用到的实例化参数类
#ifndef _PEOPLE_H
#define _PEOPLE_H
#include <iostream>
using namespace std;
class pq1;
class pq2;
template<class T,class D>
class people
{
public:
T age;
people()
{}
~people()
{}
virtual void out()
{
cout<<"base"<<endl;
}
void print()
{
cout<<"base_print"<<endl;
}
private:
};
class BlackP
{
public:
BlackP();
~BlackP();
void print();
void b_print();
static string area;
private:
};
BlackP::BlackP()
{
}
BlackP::~BlackP()
{
}
void BlackP::print()
{
cout<<"b_self_print"<<endl;
}
void BlackP::b_print()
{
cout<<"b_self_B_print"<<endl;
}
class WhiteP
{
public:
WhiteP();
~ WhiteP();
void print();
void w_print();
private:
};
WhiteP:: WhiteP()
{
}
WhiteP::~ WhiteP()
{
}
void WhiteP::print()
{
cout<<"w_self_print"<<endl;
}
void WhiteP::w_print()
{
cout<<"w_self_W_print"<<endl;
}
class CommP
{
public:
CommP();
~CommP();
private:
};
CommP::CommP()
{
}
CommP::~CommP()
{
}
#endif
CPP文件实例化类模板，并重写类模板中的虚函数
#ifndef _PEOPLE_H
#include"people.h"
#endif
#include<string>
people<int,BlackP> p1;
people<double,WhiteP> p2;
string BlackP::area;
void people<int,BlackP>::out()
{
cout<<"int_out"<<endl;
//this->print();
BlackP::area="africa";
cout<<BlackP::area<<endl;//must include string.h if you want to cout string
BlackP p;
p.b_print();
}
void people<double,WhiteP>::out()
{
cout<<"double_out"<<endl;
WhiteP p;
p.w_print();
}
int main()
{
people<double,CommP> p0;
p0.out();
p0.print();
p1.out();
p1.print();
p2.out();
system("pause");
}
