boost::algorithm::clamp() in C++ library

const T& clamp ( const T& val, const T& lo, const T& hi )
or 
const T& clamp ( const T& value, const T& low, const T& high, Pred p )

• value: This specifies the value compared to.
• low: This specifies the lower range.
• high: This specifies the higher range.
• p: This specifies the predicate function.
Return Value: The function returns three values as described below:
• It returns low if value is less than low.
• It returns high if high is greater than value.
• In all other cases, it returns value.
Program-1: CPP

// C++ program to implement the
// above mentioned function

#include <bits/stdc++.h>
#include <boost/algorithm/clamp.hpp>
using namespace std;

// Drivers code
int main()
{

    int value = 5;
    int low = 10, high = 20;

    // Function used
    int ans
        = boost::algorithm::clamp(value, low, high);

    cout << ans;
    return 0;
}

Output:

10

Program-2: CPP

// C++ program to implement the
// above mentioned function

#include <bits/stdc++.h>
#include <boost/algorithm/clamp.hpp>
using namespace std;

// Drivers code
int main()
{

    int value = 25;
    int low = 10, high = 20;

    // Function used
    int ans
        = boost::algorithm::clamp(value, low, high);
    cout << ans;
    return 0;
}

Output:

20

Program-3: CPP

// C++ program to implement the
// above mentioned function

#include <bits/stdc++.h>
#include <boost/algorithm/clamp.hpp>
using namespace std;

// Drivers code
int main()
{

    int value = 15;
    int low = 10, high = 20;

    // Function used
    int ans
        = boost::algorithm::clamp(value, low, high);
    cout << ans;
    return 0;
}

Output:

15
