8-Bit Register Class

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

// Define Reg8 class here

class Reg8 {
    private:
    uint8_t registerValue;

    public:

        registerValue = 0;
      }
      void write (uint8_t v){

      uint8_t read(){

           if (bit >= 0 && bit <= 7) {
            registerValue |= (1 << bit);
           }
      }
      void clearBit(int bit){
           if (bit >= 0 && bit <= 7) {
            registerValue &= ~(1 << bit);

int main() {

    Reg8 reg;
