#includeIn this example, we create a new FloatArray instance called `nums`. We then use the isEmpty method to check if the array is empty or not and output the result. Since we haven't yet added any elements to the array, it should return true and output "The array is empty." We then add a single element to the array using the `append` method and check the isEmpty method again. This time it should return false and output "The array is not empty." Based on the use of the FloatArray class in the code examples, it is likely that the library package is designed for numerical analysis or scientific computing, where working with arrays of floating-point numbers is common.#include int main() { FloatArray nums; if(nums.isEmpty()) { std::cout << "The array is empty." << std::endl; } else { std::cout << "The array is not empty." << std::endl; } nums.append(3.14); if(nums.isEmpty()) { std::cout << "The array is empty." << std::endl; } else { std::cout << "The array is not empty." << std::endl; } return 0; }
