本文通过一个C++程序示例展示了如何使用函数重载来实现不同类型的最大值计算，包括整型和浮点型的最大值计算，并且演示了如何通过重载处理多个参数的情况。
#include<iostream>
using namespace std;
int max (int, int);
float max(float, float);
int max (int , int, int);
int main()
{
int a = 3, b = 5, c = 7, d = 0, e = 0;
float m = 2.5, n = 4.5, k = 0.0;
d = max(a, b);
cout<<a<<","<<b<<",max="<<d<<endl;
k = max(m, n);
cout<<m<<","<<n<<",max="<<k<<endl;
e = max(a, b, c);
cout<<a<<","<<b<<","<<c<<",max="<<e<<endl;
return 0;
}
int max (int x, int y)
{
return x > y ? x : y;
}
float max(float x, float y)
{
return x > y ? x : y;
}
int max(int x, int y, int z)
{
int temp;
temp = x > y ? x : y;
return temp > z ? temp : z;
}
using namespace std;
int max (int, int);
float max(float, float);
int max (int , int, int);
int main()
{
int a = 3, b = 5, c = 7, d = 0, e = 0;
float m = 2.5, n = 4.5, k = 0.0;
d = max(a, b);
cout<<a<<","<<b<<",max="<<d<<endl;
k = max(m, n);
cout<<m<<","<<n<<",max="<<k<<endl;
e = max(a, b, c);
cout<<a<<","<<b<<","<<c<<",max="<<e<<endl;
return 0;
}
int max (int x, int y)
{
return x > y ? x : y;
}
float max(float x, float y)
{
return x > y ? x : y;
}
int max(int x, int y, int z)
{
int temp;
temp = x > y ? x : y;
return temp > z ? temp : z;
}
