找了一个c++,classtemplate的例子，为啥不能编译通过？

[kofwr]

// class templates
#include <iostream>
using namespace std;

template <class T>
class pair {
T a, b;
public:
pair (T first, T second)
{a=first; b=second;}
T getmax ();
};

template <class T>
T pair<T>::getmax ()
{
T retval;
retval = a>b? a : b;
return retval;
}

int main () {
pair <int> myobject (100, 75);
cout << myobject.getmax();
return 0;
}


错误输出：

在VS2003上面可以编过，输出100

应该是跟标准库里的名字起冲突了。
在我的编译器上（g++ 3.4.4），把所有的“pair”改在另外一个名字就没问题了。

template <class T>
class pair1 {
T a, b;
public:
pair1 (T first, T second)
{a=first; b=second;}
T getmax ();
};

template <class T>
T pair1<T>::getmax ()
{
T retval;
retval = a>b? a : b;
return retval;
}

。。。。。。。。。。。。。

就看了一会就慢了，
郁闷啊

都四星了，还为这80分郁闷。。。
