valarray min() in C++

The min() function is defined in valarray header file. This function returns the smallest value contained in the valarray.

Syntax:

T min() const;

Returns: This function returns the minimum value in the valarray.

Below programs illustrate the above function:

Example 1:-

// C++ program to demonstrate
// example of min() function.

#include <bits/stdc++.h>
using namespace std;

int main()
{
    // Initializing valarray
    valarray<int> varr = { 3, 2, 1, 4, 5 };

    // Displaying minimum element of valarray
    cout << "The smallest element"
         << " of valarray is = "
         << varr.min() << endl;

    return 0;
}

Output:

The smallest element of valarray is = 1

Example 2:-

// C++ program to demonstrate
// example of min() function.

#include <bits/stdc++.h>
using namespace std;

int main()
{
    // Initializing valarray
    valarray<int> varr = { 22, 24, 36, 42, 12 };

    // Displaying minimum element of valarray
    cout << "The smallest element "
         << "of valarray is = "
         << varr.min() << endl;

    return 0;
}

Output:

The smallest element of valarray is = 12
