seed_seq::size

seed_seq::param

std::size_t size() const;		(since C++11)

Returns the size of the stored initial seed sequence.

Parameters

(none)

Return value

The size of the private container that was populated at construction time.

Complexity

Constant time.

Exeptions

(none)	(until C++17)
noexcept specification: noexcept	(since C++17)

Example

Run this code

#include <random>
#include <iostream>
int main()
{
    std::seed_seq s1 = {-1, 0, 1};
    std::cout << s1.size() << '\n';
}

Output:
