程序源码：

#include<iostream>
using namespace std;

template <typename T1=int,typename T2=double>
class HoldsPair
{
private:
	T1 Value1;
	T2 Value2;
public:
	HoldsPair(const T1& value1, const T2& value2)
	{
		Value1 = value1;
		Value2 = value2;
	};
	const T1 & GetFirstvalue() const
	{
		return Value1;
	};
	const T2& GetSecondvalue() const
	{
		return Value2;
	};
};
int main()
{
	HoldsPair<> mIntFloatPair(300, 10.09);
	HoldsPair<short，char*> mshortstringPair(25, "learn template,love c++");
	cout << "the first object conntains-" << endl;
	cout << "Value 1:" << mIntFloatPair.GetFirstvalue() << endl;
	cout << "Value 2:" << mIntFloatPair.GetSecondvalue() << endl;

	cout << "the second object contains-:" << endl;
	cout << "Value 1:" << mshortstringPair.GetFirstvalue() << endl;
	cout << "Value 2:" << mshortstringPair.GetSecondvalue() << endl;
	return 0;
}

出现错误的原因是这一行：HoldsPair<short，char*> mshortstringPair(25, "learn template,love c++");

系统提示：没有与参数列表匹配的构造函数HoldsPair<T1,T2>::HoldsPair[其中T1=short,T2=char*]实例

把<short,char*>改成<short,const char*>就可以编译成功
