Packet Buffer Alias

#include <iostream>
#include <cstdint>

using namespace std;

// Alias for a fixed-size array of 8 bytes
using Packet = uint8_t[8];

int main() {
    Packet pkt;
    int temp[8];

    // Read input into integer array
    for (int i = 0; i < 8; i++) {
        cin >> temp[i];
    }

    // Explicitly cast integers into byte buffer
    for (int i = 0; i < 8; i++) {
        pkt[i] = static_cast<uint8_t>(temp[i]);
    }

    // Print numeric values
    for (int i = 0; i < 8; i++) {
        cout << static_cast<unsigned int>(pkt[i]);
        if (i < 7) {
            cout << " ";
        }
    }

    return 0;
}
