C++类模板的问题

Question

文档里有这样的一个范例，我在程序里运行时老是报错。大神看一下，怎么改。#include <iostream>using namespace std;template <class T> class pair{ T value1, value2; public: pair(T first, T second) { value1 =first; value2=second; } T getmax(); };template <class T>T pair::getmax (){ T retval; retval = value1>value2? value1:value2; return retval;};int main() { pair myobject(100,75); cout<<myobject.getmax(); return 0;}运行时提示：#include <iostream>using namespace std;template <class T> class pair{T value1, value2;public:pair(T first, T second) {value1 =first;value2=second;}T getmax(); };template <class T>T pair::getmax (){T retval;retval = value1>value2? value1:value2;return retval;};int main() {pair myobject(100,75);cout<<myobject.getmax();return 0;}
