arithmetic_sequence

template<typename T, typename U>
impl-dfn-deferred-range arithmetic_sequence(T start, U difference)

Creates a deferred sequence of infinite size. As the name implies, the sequence is an arithmetic sequence.

Parameters

  • start - the first element of the sequence.
  • difference - the difference of the two consecutive elements.

Each consecutive element is computed using the formula

int next = current + difference; //initially current is start.

Return

A deferred-range of infinite size. Since the returned range is an infinite range, 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 numbers = arithmetic_sequence(10, 7)  //infinite sequence!
                 | take (6) ;                  //take first 6 elements
                
    for(int i : numbers)
        std::cout << i << " ";
}

Output

10 17 24 31 38 45
