Packet Buffer Alias

#include <iostream>
#include <cstdint>

using namespace std;

using Packet = uint8_t[8];

int main() {
    
    Packet buffer;
    int temp[8]={0};
        
    for(int i=0; i<8; i++){
        cin >> temp[i];
    }
    
    for(int i=0; i<8; i++){
        buffer[i] = static_cast<uint8_t>(temp[i]);
    }    

    for(int i=0; i<8; i++){
        cout << static_cast<uint32_t>(buffer[i]);
        if(i<7){
            cout << " ";
        }
    }
