stl min函数
C ++ STL std :: min()函数 (C++ STL std::min() function)
min() function is a library function of algorithm header, it is used to find the smallest value from given two values, it accepts two values and returns the smallest value and if both the values are the same it returns the first value.
min()函数是算法标头的库函数,用于从给定的两个值中查找最小值,它接受两个值并返回最小值,如果两个值相同,则返回第一个值。
Note:To use min() function – include <algorithm> header or you can simple use <bits/stdc++.h> header file.
注意:要使用min()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::min() function
std :: min()函数的语法
std::min(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: T – it returns the smallest value of type T.
返回值: T –返回类型T的最小值。
Example:
例:
Input:
int a = 10;
int b = 20;
//finding smallest value
cout << min(a,b) << endl;
Output:
10
C ++ STL程序演示了std :: min()函数的使用 (C++ STL program to demonstrate use of std::min() function)
In this example, we are going to find the smallest values from given values of different types.
在此示例中,我们将从不同类型的给定值中找到最小值。
#include <iostream>
#include <algorithm>
using namespace std;
int main()
{
cout << "min(10,20) : " << min(10, 20) << endl;
cout << "min(10.23f,20.12f): " << min(10.23f, 20.12f) << endl;
cout << "min(-10,-20) : " << min(-10, -20) << endl;
cout << "min('A','a') : " << min('A', 'a') << endl;
cout << "min('A','Z') : " << min('A', 'Z') << endl;
cout << "min(10,10) : " << min(10, 10) << endl;
return 0;
}
Output
输出量
min(10,20) : 10
min(10.23f,20.12f): 10.23
min(-10,-20) : -20
min('A','a') : A
min('A','Z') : A
min(10,10) : 10
