简单的C++ template实例

 #include <iostream> #include <string> using namespace std;template<class T>T MaxNum(T x,T y){return (x > y ? x : y);}template <class CC>class CMaxNum{public:CC m_x,m_y;CMaxNum(CC x,CC y){m_x = x;m_y = y;}CC GetMaxNum(){return (m_x > m_y ? m_x : m_y);}};int _tmain(void){int nMax = MaxNum(10,12);cout<<nMax<<endl;float fMax = MaxNum(10.0f,55.2f);cout<<fMax<<endl;double dMax = MaxNum(10.10f,12.11f);cout<<dMax<<endl;CMaxNum<int>nMyMax(20,30);int ret = nMyMax.GetMaxNum();cout<<ret<<endl;return 0;}
