c 类中模版成员函数-ag真人游戏

c 函数模版与类模版。

template 
void swapfunction(t &first, t &second){
}//函数模版

template //类模版

class ctemplate{

public:

    void swap(t &first, t &second){

    }

};

#include 
class single{
public:
    static single*  shareinstance();
    static void releaseinstance();
     template//要成员函数实现模版用法，而类不是模版类。需要写成这个格式

    }
