overload max-重载max函数
//overload max函数
#include<iostream>
double max(double a,double b);
double max(double a,double b,double c);
int main()
{
using namespace std;
double maxoftwo,maxofthree;
double a = 3,b = 7;
double x = 1.1,y = 2.2,z = 3.3;
maxoftwo = max(a,b);
maxofthree = max(x,y,z);
cout<<"Max of the two numbers is:"<<maxoftwo<<endl;
cout<<"Max of the three numbers is:"<<maxofthree<<endl;
return 0;
}
double max(double a,double b)
{
if(a > b)
return a;
return b;
}
double max(double a,double b,double c)
{
double tem;
tem = a >b?a:b;
return c>tem?c:tem;
}结果：
Max of the two numbers is:7 Max of the three numbers is:3.3
