Number Gusser in c++ using function and midpoint

Question

I am trying to write a code for number gusser using funcitons: The playOneGame function should have a return type of void. It should implement a complete guessing game on the ra

Answer 1

The guessing loop should loop something like this:

while (true)
{
    int guess = getMidpoint(minimum, maximum);
    std::cout << "\nIs it [h]igher/[l]ower/[e]qual to " << guess << "? ";
    char answer;
    if (!(std::cin >> answer))
    {
        std::cerr << "error reading user input, program exiting\n";
        exit(1);
    }
    if (answer == 'h')
        minimum = guess + 1;
    else if (answer == 'l')
        maximum = guess - 1;
    else if (answer == 'e')
    {
        std::cout << "Well, isn't that nice.\n";
        return;
    }
    if (minimum > maximum)
    {
        std::cerr << "hey, you lied to me!\n";
        exit(1);
    }
}
