#includeIn this example, we assume that there is a package library called `FloatArray.h`. We create two FloatArrays `a` and `b`, and use the `add()` function to add them together and create `c`. We do the same thing with two other arrays `d` and `e`, and create `f`. The resulting arrays `c` and `f` are stored in new FloatArray objects. The `FloatArray` class could be a user-defined class, or it could be part of a larger library for handling matrices or vectors of floating-point values. Without more context, it's difficult to say for sure which library the `FloatArray` class comes from.// assuming this is the package library int main() { FloatArray a = {1.0, 2.5, 3.2}; FloatArray b = {0.3, 1.2, 2.0}; FloatArray c = a.add(b); // {1.3, 3.7, 5.2} FloatArray d = {5.5, 2.1}; FloatArray e = {3.2, 1.9}; FloatArray f = d.add(e); // {8.7, 4.0} return 0; }
