Hello Frank,

For plain arrays you can use std::fill from standard library:

#include <iostream>

int main() {
        double array[10];
        std::fill(std::begin(array), std::end(array), 0.0);

        for (int i = 0; i < 10; ++i) {
                std::cout << array[i] << "\n";
        }

        return 0;
}

Alternatively, you could use std::array that have compilation time defined size:

#include <iostream>
#include <array>

int main() {
        std::array<double, 10> array;
        array.fill(0.0);

        for (auto d : array) {
                std::cout << d << "\n";
        }

        return 0;
}

I prefer to use std::fill for plain arrays, because it is probable solution and works outside U++, however it requires c++17 standard. However, if your app is designed to work with Upp framework than you can freely use Upp::Zero, which is easy to use (easier than std::fill).

Sincerely,
Klugier

U++ - one framework to rule them all.
