std::uniform_real_distribution a() method in C++ with Examples

The a() method of uniform_real_distribution class in C++ is used to get the lower bound of this uniform_real_distribution.

Syntax:

result_type a() const;

Parameters: This method do not accepts any parameters.

Return Value: This method return the ‘a’ parameter in the distribution, which is the lower bound or the minimum possibly generated value in this uniform_real_distribution.

Example:

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

#include <iostream>

// for uniform_real_distribution function
#include <random>

using namespace std;

int main()
{
    double a = 10, b = 20.5;

    // Initializing of uniform_real_distribution class
    uniform_real_distribution<double> distribution(a, b);

    // Using a()
    cout << "Lower Bound: "
         << distribution.a() << endl;

    return 0;
}

Output:

Lower Bound: 10
