#includeThe program creates an instance of FloatArray containing some data and then calls the beProductOf method with a constant factor of 2.0. The resulting array is then printed to the screen. The FloatArray class is not part of the C++ standard library, but rather a custom class created by whoever wrote the code. Therefore, it's hard to determine the package library it belongs to without further context.#include "FloatArray.h" using namespace std; int main() { float data[] = {2.1, 3.5, 4.2, 5.3, 6.0}; int size = sizeof(data)/sizeof(float); FloatArray arr(data, size); FloatArray result = arr.beProductOf(2.0); cout << "Original Array: " << arr.toString() << endl; cout << "Result Array: " << result.toString() << endl; return 0; }
