template 
class SensorPair {
public:
    T_Value value;
    T_Meta metadata;

    SensorPair(T_Value v, T_Meta m) : value(v), metadata(m) {}

    void print() {
        std::cout << "Pair: " << value << " | " << metadata << std::endl;
    }
};

int main() {

    if (!(std::cin >> N)) return 0;

    std::cout << std::fixed << std::setprecision(2);

    for (int i = 0; i < N; ++i) {
        std::string type;
        std::cin >> type;

        if (type == "f-i") {
            float v; int m;

        } else if (type == "i-c") {
            int v; char m;
            std::cin >> v >> m;
            SensorPair p(v, m);
            p.print();
        } else if (type == "i-i") {
            int v; int m;
            std::cin >> v >> m;
            SensorPair p(v, m);
            p.print();
        }
    }
    return 0;
}

Explanation & Logic Summary:

Uses class templates with two type parameters
Eliminates duplicated struct definitions
Demonstrates compile-time type specialization
No runtime overhead or dynamic allocation
Output formatting handled via standard I/O manipulators

Firmware Skill Relevance:

Models heterogeneous telemetry data
Reflects real-world sensor + metadata pairing
Reinforces zero-overhead abstractions
Encourages reusable, type-safe firmware design patterns
