The a() method of uniform_int_distribution class in C++ is used to get the lower bound of this uniform_int_distribution. If there is no lower bound then this method returns 0.
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_int_distribution. Its default value is 0.
Example:
// C++ code to demonstrate // the working of a() 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 a()
cout << "Lower Bound: "
<< distribution.a() << endl;
return 0;
} |
Output:
Lower Bound: 10
