8-Bit Register Class

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

// Define Reg8 class here
class Reg8 {
    private:
        uint8_t reg;
    public:
        Reg8():reg(0){}
        void write(uint8_t v) {reg = v;}
        uint8_t read() {return reg;}
        void setBit(int bit) {
            if (bit >= 0 && bit <=7) reg = reg | (1<<bit);
        }
        void clearBit(int bit){
            if (bit>=0 && bit<=7) reg = reg & (~(1<<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());
    return 0;
}
