c++ 找最大值函数模板使用

#include <iostream>
using namespace std;
template<typename T>T Max(T x, T y);
int Max(int x, int y) {
    return x > y ? x : y;
}

int main() {
    int x = 1, y = 2;
    cout << Max(x, y) << endl;
    double douX = 3.4, douY = 5.6;
    cout << Max<double>(douX, douY) << endl;
    cout << Max('A', 'B')<<endl;
    system("pause");
    return 0;
}
template <typename T>
T Max(T x, T y) {
    return x > y ? x : y;
}


// 函数和普通函数的使用
#include <iostream>
using namespace std;
template <typename T>
T Max(T x, T y) {
    return x > y ? x : y;
}
template<typename T>
T Max(T a[],int n)
{
    T max = a[0];
    for (int i = 0; i < n; i++)
    {
        if (max<a[i])
        {
            max = a[i];
        }
    }
    return max;
}
int main() {
    cout << Max(4, 5) << endl;
    int b[] = { 2,4,5,10,4,2 };
    cout << Max(b,sizeof(b)) << endl;
    system("pause");
    return 0;
}

// 
#include <iostream>
using namespace std;
int Max(int x, int y) {
    cout << "Normal Max" << endl;
    return x > y ? x : y;
}
template <typename T>
T Max(T x, T y) {
    cout << "template Max" <<sizeof(x)<< endl;
    return x > y ? x : y;
}

int main() {
    int ix = 4, iy = 6;
    char c1 = 'a', c2 = 'c';
    int res = Max(ix, iy);
    char res1 = Max(c1, c2);
    int res2 = Max(c1, c2);
    char res3 = Max(ix, iy);
    system("pause");
    return 0;
}
