Register Type Aliases

#include <iostream>
#include <cstdint>
using namespace std;

// Step 1: Create the three type aliases here:
// using Reg8  = ...
// using Reg16 = ...
// using Reg32 = ...
using Reg8  = uint8_t;
using Reg16 = uint16_t;
using Reg32 = uint32_t;

int main() {
    uint64_t raw8, raw16, raw32;
    cin >> raw8 >> raw16 >> raw32;

    // Step 2: Store the values using the alias types:
    // Reg8  r8  = ...
    // Reg16 r16 = ...
    // Reg32 r32 = ...
    Reg8  r8  = (Reg8)raw8;
    Reg16 r16 = (Reg16)raw16;
    Reg32 r32 = (Reg32)raw32;

    // Step 3: Print the formatted output:
    // Ensure values are printed numerically
    cout << "R8="  << static_cast<uint32_t>(r8)
         << " R16=" << static_cast<uint32_t>(r16)
         << " R32=" << static_cast<uint32_t>(r32);

    return 0;
