Detailed Description

ranges::views::ints

The ints view returns a range of monotonically increasing ints.

Example

#include <iostream>
#include <vector>
#include <range/v3/view/iota.hpp>
 
int main()
{
    auto numbers = ranges::views::ints(3, 7);
 
    std::cout << numbers << '\n';
}

Output

[3,4,5,6]

Syntax

auto output_range = ranges::views::ints(lower_bound, upper_bound);

Parameters

lower_bound

• Optional lower bound

upper_bound

• Exclusive upper bound
• Required when lower_bound is specified
  • To create an infinite range with a lower_bound, use ranges::unreachable as the upper_bound

output_range

• Range of monotonically increasing ints
• When an upper_bound is not specified, the range is quasi-infinite
