8-Bit Register Class

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

// Define Reg8 class here
class Reg8{
    private:
    uint8_t value;

    public:
    Reg8() noexcept : value(0) {};
    
    void write (uint8_t v) noexcept
    {
        value = v;
    }

    uint8_t read() const noexcept
    {
        return value;
    }

    void setBit(int bit) noexcept
    {
        if (0 <= bit && bit < 8)
        value |= ( 1 << static_cast<uint8_t>(bit) );
    }

    void clearBit(int bit) noexcept
    {
        if (0 <= bit && bit < 8)
        value &= ~( 1 << static_cast<uint8_t>(bit) );
    }

int main() {
    int initialValue;
    int bitToSet, bitToClear;

    cin >> initialValue >> bitToSet >> bitToClear;

    Reg8 reg;
    reg.write(static_cast<uint8_t>(initialValue));
    reg.setBit(bitToSet);
    reg.clearBit(bitToClear);

    cout << static_cast<int>(reg.read());
