Am new to using c++20 ranges. One question I have is if you have two iterators into a vector how do you create a ranges view from them ? Range would start at first iterator and end 1 before the second iterator.

std::ranges::subrange allows combining together an iterator and a sentinel into a single view.
For example:
#include <iostream>
#include <vector>
#include <ranges>
int main()
{
std::vector v = {1, 2, 3, 4, 5};
std::ranges::subrange w(v.begin(), v.begin() + 2);
for (auto i : w)
std::cout << i << std::endl;
}
