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
    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>
    Packet arr1;
     for(int i = 0; i<8; i++){
        arr1[i] = static_cast<uint8_t>(arr[i]);
     }
    
    // 5. Print values as numbers with space separation (no trailing space)
    for(int i = 0; i<8; i++){
        cout<<static_cast<int>(arr1[i])<<" ";
    }
    
    return 0;
}
