Register8 Equality Operator

Question

Problem: Register8 Equality Operator. Solve this hands-on electronics task on EWskills.

Accepted Answer

#include 
#include 
using namespace std;

class Register8 {
private:
    uint8_t value;
public:
    Register8(uint8_t v) : value(v) {}

    bool operator==(const Register8& other) const {
        return value == other.value;
    }

    uint8_t getValue() const {
        return value;
    }
};

int main() {
    int a, b;
    cin >> a >> b;

    Register8 r1(static_cast(a));
    Register8 r2(static_cast(b));

    if (r1 == r2)
        cout << "Equal";
    else
        cout << "Not Equal";

    return 0;
}

Explanation & Logic Summary:
The overloaded == operator compares the internal 8-bit values of two Register8 objects.

If both stored values are identical, it returns true; otherwise, it returns false.

This allows register objects to be compared naturally using:

if (reg1 == reg2)

Firmware Relevance & Real-World Context:

Mirrors real firmware scenarios where hardware registers are compared
Reinforces operator overloading for cleaner low-level APIs
Emphasizes fixed-width integer types, critical in embedded systems
Encourages readable, maintainable firmware code
