std::uniform_int_distribution b() method in C++ with examples

The b() method of uniform_int_distribution class in C++ is used to get the upper bound of this uniform_int_distribution. If there is no upper bound then this method returns std::numeric_limits::max().

Syntax:

result_type b() const;

Parameters: This method do not accepts any parameters.

Return Value: This method return the ‘b’ parameter in the distribution, which is the upper bound or the maximum possibly generated value in this uniform_int_distribution. Its default value is std::numeric_limits::max().

Example:

// C++ code to demonstrate
// the working of b() function

#include <iostream>

// for uniform_int_distribution function
#include <random>

using namespace std;

int main()
{
    int a = 10, b = 100;

    // Initializing of uniform_int_distribution class
    uniform_int_distribution<int> distribution(a, b);

    // Using b()
    cout << "Upper Bound: "
         << distribution.b() << endl;

    return 0;
}

Output:

Upper Bound: 100
