重载函数取最大值

[c++]代码库

#include "stdafx.h"
#include "iostream"
using namespace std;
int max1(int x, int y, int z)  //3个整数的最大值
{	
	int m;
	int n;
	if (x > y)m = x;
	else m = y;
	if (m > z)n = m;
	else n = z;
	return(n);
}
double max2(double a, double b,double c)//3个双精度数的最大值
{
	double mm;
	double nn;
	if (a>b)mm = a;
	else mm = b;
	if (mm>c)nn = mm;
	else nn = c;
	return(nn);

}
int main()
{
	int x, y, z;
	double a, b, c;
	cout<<"input 3 integers"<<endl;
	cin>>x>>y>>z;//输入3个整数
	cout<<"最大值为"<<max1(x,y,z)<<endl;//输出其最大值
	cout<<"input 3 doubles"<<endl;
	cin>>a>>b>>c;//输入3个双精度数
	cout<<"最大值为"<<max2(a, b, c)<<endl;//输出其最大值
	return 0;
