prime_sequence

template<typename T>
impl-dfn-deferred-range prime_sequence(T start);

Creates a deferred prime sequence of infinite size.

Parameters

start - the lower bound of the sequence to be generated whose first element is start if it is a prime number or the minimum prime number greater than start.

Return

A deferred-range of infinite size. Since the returned range is an infinite sequence, it can be used with take() or take_while() processor-pipe.

Example

#include <iostream>
#include <vector>
#include <foam/composition/pipeline.h>

int main()
{
    using namespace foam::composition;

    auto primes = prime_sequence(10)  //infinite sequence
                | take(15)            //take first 15 elements

    for(int i : primes)
        std::cout << i << " ";
}

Output

11 13 17 19 23 29 31 37 41 43 47 53 59 61 67
