关于C++函数模版的实现讲解

template <类型形式参数表> 返回类型  函数名(形参)
{
  //函数实现
}

#include <cstdio>
#include <iostream>
using namespace std;
//函数模板
template <class T>
T max(T & a, T & b)  
{
 return a > b ? a : b;
}
int main(void)
{
 int x, y;
 x = 1;
 y = 4;
 cout << "max = " << max<int>(x, y) << endl;
 cout << "max = " << max<double>(1.234, 5.567) << endl;
 cout << "max = " << max(21.234f, 51.567f) << endl;
 return 0;
