#includeThis program defines a custom Vec2f struct and a distance function that uses the Vec2f distance formula. It then uses the distance function to calculate the total distance between a series of points in a vector. The package library that provides the Vec2f distance function is likely to be a mathematical or vector graphics library, such as SFML or Boost.Geometry.#include #include struct Vec2f { float x, y; }; float distance(Vec2f a, Vec2f b) { float dx = b.x - a.x; float dy = b.y - a.y; return std::sqrt(dx * dx + dy * dy); } int main() { std::vector points; points.push_back({2, 3}); points.push_back({4, 1}); points.push_back({6, 5}); float total_distance = 0; for (int i = 0; i < points.size() - 1; i++) { total_distance += distance(points[i], points[i+1]); } std::cout << "Total distance: " << total_distance << std::endl; return 0; }
