max和min未定义

#include <iostream>
#icnlude <algorithm>

using namespace std;

int main()
{
cout << "Please enter two number:";
int a,b;
cin >> a >> b;

cout << "a+b=" << a+b << "\n";
cout << "a-b=" << a-b << "\n";
cout << "axb=" << a*b << "\n";
cout << "(a+b)/2=" << (a+b)/2 << "\n";
cout << "|a-b|=" << abs(a-b) << "\n";
cout << "max of a and b is " << max(a, b)
cout << "min of a and b is " << min(a, b)
return 0;
}

编译提示error: max and min 未定义？这是为什么啊
问题解决了
原来是要把
#include <algorithm>-->#include "windef.h"
供大家参考
谢谢大家的回答

对啊~~
你的max 和min就没有定义~~~

提示是对的~~

这样定义~~：
int max(int a, int b)
{
return a>b?a:b;
}

int min(int a, int b)
{
return a<b?a:b;
}

#include <iostream>
#include <algorithm>

using namespace std;

int main()
{
cout << "Please enter two number:";
int a,b;
cin >> a >> b;

cout << "a+b=" << a+b << "\n";
cout << "a-b=" << a-b << "\n";
cout << "axb=" << a*b << "\n";
cout << "(a+b)/2=" << (a+b)/2 << "\n";
cout << "|a-b|=" << abs(a-b) << "\n";
cout << "max of a and b is " << max(a, b);
cout << "min of a and b is " << min(a, b);
