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 = static_cast<Reg8>(raw8);
    Reg16 r16 = static_cast<Reg16>(raw16);
    Reg32 r32 = static_cast<Reg32>(raw32);

    // Step 3: Print the formatted output:
    // Ensure values are printed numerically
    cout << "R8="<<(int)r8 << " "<<"R16="<<(int)r16<< " "<<"R32="<<(int)r32;
    return 0;
}
