Answer 1

#include <iostream>

template<typename T>
bool PairCompare(T a, T b) {
    return a == b;
}

template<typename T, typename... Args>
bool PairCompare(T a, T b, Args... args) {
  return a == b && PairCompare(args...);
}

int main() {
    std::cout << PairCompare(3, 3, 7.8, 7.8, 99, 99, 0.17, 0.17) << "\n";
    std::cout << PairCompare(3, 3, 7.8, 7.8, 99, 99, 5, 6) << "\n";
}
