Unfortunately, there is no widely-known or standard package library called "FloatArray zero" in C++. However, it is possible to infer from your question that you are interested in creating a C++ class for a dynamically-sized array of floating-point numbers, with functionality to initialize all elements to zero.
Here's an example implementation of such a class:
```c++
#include
#include
class FloatArray {
public:
FloatArray(int n) : data(n, 0.0) {}
float& operator[](int i) { return data[i]; }
float operator[](int i) const { return data[i]; }
int size() const { return data.size(); }
private:
std::vector data;
};
int main() {
FloatArray a(10);
for (int i = 0; i < a.size(); i++) {
std::cout << a[i] << " "; // prints "0 0 0 0 0 0 0 0 0 0"
}
std::cout << std::endl;
a[5] = 1.23;
std::cout << a[5] << std::endl; // prints "1.23"
}
```
In this implementation, the `FloatArray` class internally uses a `std::vector` to store the array elements, and initializes all elements to 0.0 in the constructor using the `std::vector` constructor that takes a size and a default value.
The `operator[]` overloads allow for array-like access to the elements, with the non-const version allowing for element modification. The `size()` method returns the number of elements in the array.
In the `main()` function, a `FloatArray` object `a` with 10 elements is created and initialized to all zeros. Then, the array elements are printed to the console using the `[]` operator and modified by assigning a value to `a[5]`.
