Packet Buffer Alias

#include <iostream>
#include <cstdint>

using namespace std;

// 1. Create the alias for an array of 8 bytes:
using Packet = uint8_t[8];

int main() {
    // 2. Declare a variable of type Packet and a temporary int array
    Packet p;
    int arr[8];
    // 3. Read 8 integers into the temporary array
    for(int i=0;i<8;i++){
        cin>>arr[i];
    // 4. Assign values to the Packet buffer using static_cast<uint8_t>
        p[i]=static_cast<uint8_t>(arr[i]);
    // 5. Print values as numbers with space separation (no trailing space)
        cout<<(static_cast<uint32_t>(p[i]))<<" ";
    }
    return 0;
}
