Web1 day ago · Since we are comparing a member variable of the cat to 0, in C++17 we need to use std::find_if and pass a closure which accesses that member and does the comparison. Since the rangified algorithms support projections, in C++20 we can use std::ranges::find and pass &cat::age as a projection, getting rid of the need for the lambda completely.
