std::seed_seq

Member functions

seed_seq::seed_seq

seed_seq::generate

seed_seq::size

seed_seq::param

 

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

Returns the size of the underlying seed sequence.

Return value

v .size()

Complexity

Constant time.

Example

Run this code

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

Output:

3
