WebBoth can be combined on today’s modern SIMD CPUs with multiple cores. In theory, either of these should be faster than single-thread serial calculation. In practice, however, there is a certain amount of overhead involved in setting up either kind of parallelism. Web23 hours ago · Since we are comparing a member variable of the catto 0, in C++17 we need to use std::find_ifand 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::findand pass &cat::ageas a projection, getting rid of the need for the lambda completely.
