#includeIn this example, we first create two FloatRect objects with different positions and sizes. We then call the unite function on rect1, passing in rect2 as the argument. This creates a new FloatRect that covers both of the original rectangles, which we store in a variable called combined. Finally, we print out some of the properties of the combined rectangle to verify that it covers both of the original rectangles. The SFML library is a collection of C++ classes and functions for building multimedia applications. It includes support for graphics, audio, input handling, and networking, among other things. The FloatRect unite function is part of the SFML graphics module, which provides classes for working with 2D graphics.int main() { sf::FloatRect rect1(10, 10, 50, 50); sf::FloatRect rect2(30, 30, 80, 80); sf::FloatRect combined = rect1.unite(rect2); std::cout << "Combined rect top: " << combined.top << std::endl; std::cout << "Combined rect left: " << combined.left << std::endl; std::cout << "Combined rect width: " << combined.width << std::endl; std::cout << "Combined rect height: " << combined.height << std::endl; return 0; }
