包含在c++標準庫中標頭檔案中，在標頭檔案<windows.h>中定義了min,max的巨集，若在包含的同時包含<windows.h>會導致函式無法使用。

<windows.h>提供了_cpp_min等函式來代替min函式的功能。

C++11標準：中min函式的原型

• Return the smallest

• Returns the smallest of a and b. If both are equivalent, a is returned.

• The versions for initializer lists (3) return the smallest of all the elements in the list. Returning the first of them if these are more than one.

The function uses operator< (or comp, if provided) to compare the values.

eg:custom2<pre style="margin-top: 0px; margin-bottom: 0px; color: rgb(0, 128, 0);">template <class T, class Compare>
  const T& min (const T& a, const T& b, Compare comp);

#include<iostream>
#include<algorithm>
using namespace std;
struct var {
	char *name;
	int key;
	var(char *a,int k):name(a),key(k){}
};
bool comp(const var& l, const var& r) {
	return l.key < r.key;
}
int main() {
	var v1("var1", 2);
	var v2("var2", 3);
	cout << std::min(v1, v2,comp).name << endl;
	return 0;
}
 

stable_sort,max函式同min
