1.模板申明tempate <typename T,typename T2,......>
2.模板使用函数名<实际类型1，实际类型2,......>(函数参数列表......)

#include <stdlib.h>
#include <iostream>
using namespace std;

template <typename T>

void SwapData(T &a, T &b)
{
    T tempdata;
    tempdata = a;
    a = b;
    b = tempdata;
    return;
}

template <typename T1, typename T2>
void SortData(T1 *arraydata, T2 datanumber)
{
    int i = 0;
    int j = 0;
    for (i = 0; i < datanumber;i++)
        for (j = i + 1; j < datanumber;j++)
            if (arraydata[i] < arraydata[j])
                SwapData<int>(arraydata[i], arraydata[j]);
    return;
}

template <typename T1, typename T2>
void PrintData(T1 *arraydata, T2 datanumber)
{
    int i = 0;
    for (i = 0; i < datanumber; i++)
        cout << arraydata[i] << " ";
    cout << endl;
}

void main()
{
    int a = 12;
    int b = 90;
    char a1 = 'a';
    char b1 = 'b';
    SwapData <int>(a, b);
    cout << "a = " << a <<endl << "b = " << b << endl;
    SwapData <char>(a1, b1);
    cout << "a1 = " << a1 << endl << "b1 = " << b1 << endl;
    int arraydata[] = {1,6543,24,12,0,23,25,68,3,9,10};
    int arraydatalen = sizeof(arraydata) / sizeof(arraydata[0]);
    PrintData<int, int>(arraydata, arraydatalen);
    SortData<int, int>(arraydata, arraydatalen);
    PrintData<int, int>(arraydata, arraydatalen);
    system("pause");
    return;
