Packet Buffer Alias

#include <iostream>
#include <cstdint>

using namespace std;

// 1. Create the alias for an array of 8 bytes:
// using Packet = ...
using Packet = uint8_t[8];
int main() {
    // 2. Declare a variable of type Packet and a temporary int array
    Packet p;
    // 3. Read 8 integers into the temporary array
    int num;
    for(int i = 0;i<8;i++) {
        cin >> num;
    // 4. Assign values to the Packet buffer using static_cast<uint8_t>
    p[i] = static_cast<uint8_t>(num);
    }
    // 5. Print values as numbers with space separation (no trailing space)
    for(int i = 0;i<8;i++)
        cout << static_cast<int>(p[i]) << " ";
    return 0;
}
