輸入三個數，輸出最大數，最小數

#include<iostream>
#include<iomanip>
#include<cmath>
using namespace std;
int main()
{
	int a,b,c;
	cin>>a>>b>>c;
	int max,min;
	max=min=a;
	if(b>max)
	max=b;
	if(c>max)
	max=c;
	if(b<min)
	min=b;
	if(c<min)
	min=c;
	cout<<"The maximum number is : "<<max<<endl;
	cout<<"The minimum number is : "<<min<<endl;
	return 0;
 }
