You know how it works

int main() {

    int num1 = getFirstNum();
    int num2 = getSecondNum();

    int avg = (num1 + num2) / 2;
}

Average, what can go wrong?

int main() {

    int num1 = getFirstNum();
    int num2 = getSecondNum();

    int avg = std::________(num1, num2);
}

What can we use to have a safe avg?

int main() {

    int num1 = getFirstNum();
    int num2 = getSecondNum();

    int avg = std::midpoint(num1, num2);
}

std::midpoint, since C++20
