c++minmax函数

## C ++ STL std :: minmax()函数 **(**C++ STL std::minmax() function**)** ##

**minmax() function** is a library function of **algorithm** header, it is used to find the smallest and largest values, it accepts two values and returns a pair of the smallest and largest values, the first element of the pair contains the smallest value and the second element of the pair contains the largest value.

**minmax()函数**是**算法**标头的库函数，用于查找最小和最大值，它接受两个值并返回一对最小和最大值，该对中的第一个元素包含最小值，并且该对中的第二个元素包含最大值。

**Note:**To use **minmax() function** – include <algorithm> header or you can simple use <bits/stdc++.h> header file.

**注意：**要使用**minmax()函数** –包括<algorithm>头文件，或者您可以简单地使用<bits / stdc ++。h>头文件。

**Syntax of std::minmax() function**

**std :: minmax()函数的语法**

std::minmax(const T& a, const T& b);

**Parameter(s):** const T& a, const T& b – values to be compared.

**参数：** const T＆a，const T＆b –要比较的值。

**Return value:** pair – it returns the pair of the smallest and the largest values.

**返回值：** pair-返回最小和最大的一对。

**Example:**

**例：**

Input:
        int a = 10;
        int b = 20;
        
        //finding pair of smallest and largest numbet
        auto result = minmax(a, b);
    
        cout << result.first << endl;
        cout << result.second << endl;
        
        Output:
        10
        20

## C ++ STL程序演示std :: minmax()函数的使用 **(**C++ STL program to demonstrate use of std::minmax() function**)** ##

In this program, we have two integer variables and finding the smallest and the largest values.

在此程序中，我们有两个整数变量并找到最小和最大值。

//C++ STL program to demonstrate use of 
    //std::minmax() function
    #include <iostream>
    #include <algorithm>
    using namespace std;
    
    int main()
    {
        
        int a = -10;
        int b = -20;
    
        //finding pair of smallest and largest numbet
        auto result = minmax(a, b);
    
        //printing the smallest and largest values
        cout << "smallest number is: " << result.first << endl;
        cout << "largest number is: " << result.second << endl;
    
        return 0;
    }

**Output**

**输出量**

smallest number is: -20
    largest number is: -10
