Register Type Aliases

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

// Step 1: Create the three type aliases here:
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  = raw8;
    Reg16 r16 = raw16;
    Reg32 r32 = raw32;

    // Step 3: Print the formatted output:
    cout << "R8=" << static_cast<int>(r8) << " R16=" << r16 << " R32=" << r32 << endl;

    return 0;
}
