测试在class template中有static data members

#include "stdafx.h"
#include <iostream>
#include <assert.h>
#include <string>
#include <vector>
using namespace std;

template <typename T>
class testclass
{
public:
    static int _data;
};

int testclass<int>::_data = 1;
int testclass<char>::_data = 2;

int _tmain(int argc, _TCHAR* argv[])
{      
    cout << testclass<int>::_data << endl;
    cout << testclass<char>::_data << endl;

    testclass<int> obji1,obji2;
    testclass<char> objc1,objc2;

    cout << obji1._data << endl;
    cout << obji2._data << endl;
    cout << objc1._data << endl;
    cout << objc2._data << endl;

    obji1._data = 3;
    objc2._data = 4;

    cout << obji1._data << endl;
    cout << obji2._data << endl;
    cout << objc1._data << endl;
    cout << objc2._data << endl;

    return 0;
}
