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
