How it works...

We use the std::array template to declare a custom DataFrame data type. For our sample application, a DataFrame is a sequence of eight 32-bit integers:

using DataFrame = std::array<uint32_t, 8>;

Now, we can use the new data type in functions to generate and process data frames. Since the data frame is an array, we pass it by reference to the GenerateData function to avoid extra copying:

void GenerateData(DataFrame& frame) {

GenerateData fills the data frame with random numbers. Since std::array has the same interface as other containers in the standard library, we can use standard algorithms to make the code shorter and more readable:

 std::generate(frame.begin(), frame.end(), [&rd]() { return rd() % 100; });

We define the ...
